Interpretation: The frequency of radiation of a given wavelength needs to be determined. Also, the region in which this radiation should be in the
Concept Introduction: The relation between wavelength and frequency of radiation is as follows:
Here,
Answer to Problem 16SP
Explanation of Solution
From the given wavelength of radiation, the frequency can be calculated as follows:
Here, the value of the speed of light is constant that is
Substitute the values in the above formula,
Here,
Thus,
The below table shows the range of frequency for all the regions in the electromagnetic spectrum:
Region | Frequency range in Hz |
Gamma-rays | |
X-rays | |
Ultraviolet (UV) | |
Visible light | |
Infra-red | |
Microwave | |
Radio wave |
From the above table, it can be seen that the calculated frequency lies in the range of
The frequency of radiation of a given wavelength is
