Question

Arrange the following types of radiations in increasing order of frequency:
(a) radiation from the microwave oven
(b) amber light from a traffic signal
(c) radiation from FM radio
(d) cosmic rays from outer space and (e) X-rays.

Answer 1

The increasing order of frequency is as follows:
Radiation from FM radio < amber light < radiation from microwave oven < X- rays < cosmic rays
The increasing order of wavelength is as follows:
Cosmic rays < X-rays < radiation from microwave ovens < amber light < radiation of FM radio
