Q45 of 69 Page 65

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

As the frequency increases the wavelength decreases. The arrangement is given as below:

Cosmic rays < X-rays < radiation from microwave ovens < amber light < radiation of FM radio
