Gamma Rays
-have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancer cells.
What is the shortest wave?
Gamma rays
have the shortest wavelengths of the electromagnetic spectrum, and the highest energies.
What are the 7 electromagnetic waves in order?
The electromagnetic spectrum includes, from longest wavelength to shortest:
radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays
.
What are the sizes of electromagnetic waves?
Radio waves range
in length from very big like the size of a tall building to small like the size of a coin
. Wavelengths that SCaN currently communicates with are between the size of a building and the size of a pinhead. The two bands that SCaN does not utilize are Gamma and Cosmic Rays, which are extremely small.
What color has the highest frequency?
Violet
waves have the highest frequencies.
What are the 7 types of light?
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 highest energy?
Red has the lowest energy and
violet
the highest.
What color is the lowest frequency?
The lowest frequency of visible light, which is
red
, has the least energy.
What is the highest frequency?
The highest frequency colour, which is
violet
, also has the most energy when it comes to visible light. The lowest visible light frequency, which is red, has the least energy. There is more energy in higher-frequency waves. Gamma rays have the shortest wavelengths and highest frequencies of all electromagnetic waves.
What are the 7 electromagnetic waves and their uses?
- Radio waves: Communication.
- Microwaves: Heating and data transmission.
- Infrared waves: Used in remote control and imaging applications.
- Visible light: Help us see everything around us.
- Ultraviolet Waves: Useful in the study of galaxies.
What is the most important electromagnetic wave?
The different types of waves have different uses and functions in our everyday lives. The most important of these is
visible light
, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.
How do you detect electromagnetic waves?
To detect the electric fields,
use a conducting rod
. The fields cause charges (generally electrons) to accelerate back and forth on the rod, creating a potential difference that oscillates at the frequency of the EM wave and with an amplitude proportional to the amplitude of the wave.
What color has the least energy?
Red
is the lowest energy visible light and violet is the highest. A solid object has color depending on the light it reflects.
What are the colors that have higher frequency than red?
Blue light
has a higher frequency and carries more energy than red light. The wavelengths of light waves are very, very short, just a few 1/100,000ths of an inch.
Which color is more energetic red or yellow?
coz red
can redect energy more than yellow .
What are light waves called?
Light radiates from a source in waves. Each wave has two parts; an electric part, and a magnetic part. That’s why light is called
Electromagnetic Radiation
. … The shortest wavelengths of the spectrum are the ultraviolet, x-ray, and gamma radiation. The visible portion is a very small part of the electromagnetic spectrum.
