Ultraviolet rays have higher frequencies, from a few × 10 16 Hz, and shorter wavelengths, down to 10 – 8 m, than visible light. X-rays are emitted following electron transitions between the K, L, M and N atomic electron shells. X-ray wavelengths cover the range 10 – 8 to 10 – 11 m, with frequencies from 10 16 to 10 19 Hz.
What wave has a frequency of 10 8 Hertz?
| name ITU 1 number | very high frequency ( VHF ) (~10 8 Hz) | ultra high frequency (UHF) (~10 9 Hz) | super high frequency (SHF) (~10 10 Hz) | extremely high frequency (EHF) (~10 11 Hz) |

Which type of wave has a frequency of approximately 10-12 hertz?
Microwave frequencies range from about 10 9 Hz to the highest practical LC resonance at nearly 10 12 Hz. Since they have high frequencies, their wavelengths are short compared with those of other radio waves—hence the name “microwave.”
Which type of electromagnetic wave has a wavelength of approximately 10 10 meters?
| Region Wavelength range (approx.) Frequency range (approx.) | Long-wave radio >10 m <3×10 7 hz | Short-wave radio 10 cm – 10 m 3×10 7 – 3×10 9 | Microwave 1 mm – 10 cm 3×10 9 – 3×10 11 | Far infrared 30 mm – 1 mm 3×10 11 – 10 13 |

Which type of wave has a wavelength of 10-12 meters?
The range for X-rays is 10 – 10 to 10 – 12 meters. Gamma rays are the most energetic light waves found on the electromagnetic spectrum. We can find Gamma rays released in nuclear reactions and particle collisions. The range for a gamma ray is in picometers (10 – 12 meters).
What is the frequency of visible light in Hz?
Visible light falls in the range of the EM spectrum between infrared (IR) and ultraviolet (UV). It has frequencies of about 4 × 10 14 to 8 × 10 14 cycles per second , or hertz (Hz) and wavelengths of about 740 nanometers (nm) or 2.9 × 10 − 5 inches, to 380 nm (1.5 × 10 − 5 inches).
What is the frequency of a wave?
Frequency, in physics, the number of waves that pass a fixed point in unit time ; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Which electromagnetic wave has the highest frequency?
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
What color has the highest frequency?
Violet waves have the highest frequencies.
How do I find the frequency of a wave?
- f=1T. where: f is the frequency of the wave in hertz. T is the period of the wave in seconds.
- f=vλ where: f is the frequency of the wave in hertz. v is the velocity of the wave in meters per second. λ is the wavelength of the wave in meters. ...
- f=cλ Related topic.
Which has the longest wavelength?
Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Ultraviolet (UV) light—is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 .
What causes the frequency of a wave to increase?
Explanation: Firstly, frequency is defined as being the number of complete waves per second that pass a stationary object/point. ... So wavelength decreases as frequency increases.
What is the wave frequency of an electromagnetic wave?
Frequency=SpeedWavelength or Wavelength=SpeedFrequency. ... Consider an electromagnetic wave that has a wavelength of 3 meters. Its speed, like the speed of all electromagnetic waves, is 3.0 × 10 8 meters per second. Its frequency can be found by substituting these values into the frequency equation: Frequency=3.0× 3.0 .
What are the 7 wavelengths?
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays .
What color has the shortest wavelength?
WAVELENGTHS OF VISIBLE LIGHT
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.
Does red have high frequency?
Red light has relatively long waves, around 700 nm long. Blue and purple light have short waves, around 400 nm. Shorter waves vibrate at higher frequencies and have higher energies. Red light has a frequency around 430 terahertz , while blue’s frequency is closer to 750 terahertz.
