Light is one form of energy that travels in electromagnetic waves. This energy is both (1) and
electrical. There are many different types of electromagnetic (EM) waves. Most of them cannot be seen by humans.
Our eyes see only a small (2)
of EM waves called visible light Visible light is made up of different colors
The colors are red, orange, yellow, green, blue, indigo, and violet. The colors are due to the different (3)
of
light. The (4)
the wavelength, the less energy the wave has. The shorter the wavelength, the more energy
it has. The (5) wavelength of visible light looks red to us the shortest (6)

Explanation:

Electromagnetic waves are formed by the interference of both electric and magnetic fields. These include: Microwaves, Radio waves, Infrared, Visible, Ultraviolet, X-ray, and gamma rays. These waves can be arranged in a specific order (called spectrum) with respect to their wavelength or frequency. The higher the wavelength, the lower the frequency. And vice versa.

These waves are transverse, and travels at the same speed (speed of light - 3.0 x m/s).

In the given question, the answers are:

1 - Magnetic

2 - Region

3 - Refractive indices

4 - Greater

5 - Higher

6 - Wavelength
