Question

name the wave of wavelength nearly 9000 A​

Answer 1

Answer:

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

5

nm), micro waves (10

5

−10

8

nm), radio waves (>10

8

nm). Therefore, the range of the electromagnetic spectrum is 0.01Ato9000A.

Hence, the wave A with wavelength of 0.01A is Gamma rays and the wave B with wavelength of 9000A is radio waves.
