Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
What is the highest frequency?
Gamma rays have the highest frequency in the electromagnetic spectrum. They have a frequency of the order of about 1020 to 1022 Hz .
What is the highest and lowest frequency?
Radio waves usually have the lowest frequency , while Gamma rays have the highest frequency. And as you can see the trend is opposite for wavelength, as frequency and wavelength are inversely related.
What color radiation has the highest frequency?
The more energy a wave has, the higher its frequency, and vice versa. When it comes to visible light, the highest frequency color, which is violet , also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
What frequency has the highest frequency?
| Extremely high frequency (ITU) | Frequency range 110 to 300 GHz | Wavelength range 2.73 to 1 mm | Related bands EHF (IEEE) |
|---|
Which class has the highest frequency?
Answer:Red has the lowest at 430 trillion hertz. It also carries the lowest energy. Violet has the highest frequency at 760 trillion hertz and carries the highest energy.
What is the highest frequency humans can hear?
Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz . (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)
Which type of electromagnetic radiation has the highest energy?
Gamma rays have the highest energies and shortest wavelengths on the electromagnetic spectrum.
Which has a higher frequency visible or ultraviolet?
Ultraviolet light is located between X-radiation and visible light. UV has a higher frequency and shorter wavelength than visible light, and it has a lower frequency and longer wavelength than X-radiation.
What is the frequency range of infrared radiation?
Infrared radiation (IR radiation for short) describes electromagnetic waves in the spectral range between visible red light and longer-wave microwave radiation (also known as terahertz radiation). Infrared (IR) has wavelengths λ between 780 nm and 1 mm, which corresponds to a frequency range from 300 GHz to 400 THz.
What is the frequency range of UV radiation?
Ultraviolet (UV) light falls in the range of the EM spectrum between visible light and X-rays. It has frequencies of about 8 × 10 14 to 3 × 10 16 cycles per second , or hertz (Hz), and wavelengths of about 380 nanometers (1.5 × 10 − 5 inches) to about 10 nm (4 × 10 − 7 inches).
What is highest frequency in statistics?
| class frequency | 40 to 50 50 to 60 60 to 70 70 to 80 80 to 90 3 4 4 5 2 <= Modal class |

Which color has the highest frequency but lowest wavelength?
Violet – shortest wavelength, around 400-420 nanometers with highest frequency. They carry the most energy.
What sounds are high frequency?
Frequency is how high or low a sound is. A bass drum, thunder, and a man’s deep voice are low- frequency sounds. A high-pitched whistle, squeal, and a child’s voice are high-frequency sounds.
What is the highest frequency a child can hear?
The ‘normal’ hearing frequency range of a healthy young person is about 20 to 20,000Hz . Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there.
Can humans hear high frequency sounds?
The human hearing range is around 20 to 20,000 Hz , and as we get older, our ability to hear high-pitched sounds begins to decrease. Age, and other factors like exposure to noise, can have a big impact on the frequencies we hear. If you’re curious about the range of your hearing, we’ve got just the thing.
Which of these has the highest energy?
Answer: (c) Gamma rays
Gamma rays > X-rays > ultra-violet radiation > infrared radiation. The energy of a wave depends on its wavelength: the longer the wavelength, the lower the energy. Therefore, in the electromagnetic spectrum, gamma rays have the highest energy, and long radio waves the lowest.
Is infrared high frequency?
Infrared rays have a higher frequency than radio waves , so they have more energy than radio waves. Because you can feel the energy of infrared rays as heat, these rays are often called heat rays. Heat lamps have bulbs that give off mostly infrared rays and very little visible light.
Which has greater frequency UV radiation or violet light?
Ultraviolet radiation has shorter waves than blue or violet light, and thus oscillates more rapidly and carries more energy per photon than visible light does.
Which has a higher frequency visible or infrared radiation?
Frequency. ... The frequencies of IR waves are less than the frequencies of visible light .
What is frequency of gamma rays?
Gamma rays have frequencies greater than about 10^19 cycles per second , or hertz (Hz), and wavelengths of less than 100 picometers (pm), or 4 x 10^9 inches. (A picometer is one-trillionth of a meter.)
Which color registered the highest frequency shortest wavelength greatest energy?
Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter – roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.
Which visible color has the highest wavelength of electromagnetic radiation?
As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
Which wave is larger gamma rays or radio waves?
The sequence from longest wavelength ( radio waves) to shortest wavelength (gamma rays) is also a sequence in energy from lowest energy to highest energy. ... The energy carried by a radio wave is low, while the energy carried by a gamma ray is high. Different materials can block different types of light.
What is the range of frequencies are?
| Frequency range Wavelength range ITU designation | Full name | 300 kHz – 3 MHz 1 km – 100 m Medium frequency | 3–30 MHz 100–10 m High frequency | 30–300 MHz 10–1 m Very high frequency |

What does it mean when the UV index is very high?
A UV Index of 8-10 (Very High) means there is high risk of harm from unprotected sun exposure . ... Minimize as much sun exposure as possible during the midday hours of 10 a.m. to 2 p.m. Liberally apply a broad spectrum sunscreen of 30+ SPF.
What is high pitch frequency?
This vibration is that of a pure tone with a frequency equal to 3000 Hz , meaning over the highest frequency of the human voice (soprano: 2 100 Hz).
Which letters are high-frequency?
Consonants such as “s,” “h,” and “f ,” which have higher frequencies and are harder to hear. Because consonants transmit the majority of the meaning in speech, it would only make sense that those with high-frequency hearing loss have trouble following conversations.
Does high-frequency mean high energy?
The higher the frequency of light, the higher its energy . We know from the problems above that higher frequencies mean shorter wavelengths. ... High frequency light has short wavelengths and high energy. X-rays or gamma-rays are examples of this.
