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

Explanation

To arrange the given types of radiation in increasing order of frequency, we need to understand the relationship between wavelength and frequency. The frequency of electromagnetic radiation is inversely proportional to its wavelength; that is, as the wavelength increases, the frequency decreases.

### Step-by-Step Solution:

1. **Identify the Types of Radiation**:
- (a) Radiation from microwave oven
- (b) Amber light from traffic signal
- (c) Radiation from FM radio
