Question
Arrange the following type of radiations in increasing order of frequency:
- radiation from microwave oven
- amber light from traffic signal
- radiation from FM radio
- cosmic rays from outer space and
- X-rays.
Solution
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
