Question

Q4. A wave has a wavelength of 0.1 °A. (a) Name the wave (b) State one unique property of the wave mentioned in part 'a' different from light.​

Answer 1

Answer:

(a) Gamma waves and

Explanation:

Electromagnetic radiation is classified into types according to the frequency of the wave. These types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

The frequency is the inverse of wavelength. Hence, in the order of increasing wavelength, the waves are Gamma rays (<1nm), X-rays (1−10nm), infra red rays (700−10

nm), micro waves (10
