List the following types of electromagnetic radiation in order of decreasing wavelength:

(a) the gamma rays produced by a radioactive nuclide used in medical imaging
(b) radiation from an fm radio station at 93.1 mhzon the dial
(c) a radio signal from an am radio station at 680 khz on the dial
(d) the yellow light from sodium vapor streetlights
(e) the red light of a light-emitting diode, such as in a calculator display

Explanation:

We know that the distance between two consecutive crest and the trough is called wavelength of any wave.

(a) Gamma rays have shorter wavelength while radio wave have maximum wavelength. Wavelength of gamma rays is ranging from

(b) Frequency of FM radio station radiation,

(c) Frequency of AM radio station ,

(d) The wavelength of yellow is 597 nm.

(e) The wavelength of red light is 680 nm.

It is clear that, the decreasing order of wavelength is :

Frequency of AM radio station is 441.17 m

Frequency of FM radio station is 3.22 m

The wavelength of red light is 680 nm

The wavelength of yellow is 597 nm

The wavelength of Gamma rays is
