Answer 1

1. The frequency range of infrared radiation is c. 3 x1014 Hz - 3x1015 Hz

2. The color of light is a. Blue

3. X-ray as the highest frequency among others (option D)

4. Radio wave has the least amount of energy (option C)

5. The statement "Gamma ray has the highest frequency and the highest energy" is correct (option A)

What are EM waves?

Electromagnetic (EM) waves represent energy emitted by charged particles during acceleration. They manifest as oscillating electric and magnetic fields that travel through space, including a vacuum, at the rapid speed of light (around
`3 * 10^8` meters per second).

The electromagnetic spectrum encompasses a wide range of wavelengths and frequencies, defining the diverse array of EM waves.
