The frequency of an irradiation with wavelength of 2.54 × 10-⁷ metres is 1.18 × 10¹⁵ Hz.
How to calculate frequency?
The frequency of a radiation is the rate of occurrence of anything i.e. the relationship between incidence and time period.
The frequency of a wave can be calculated using the following formula;
λ = v/f
Where;
- λ = wavelength
- v = speed of light
- f = frequency
According to this question, an irradiation with wavelength of 2.54 × 10-⁷ metres is given. The frequency can be calculated as follows;
2.54 × 10-⁷ metres × f = 3 × 10⁸ metres/seconds
f = 3 × 10⁸ ÷ 2.54 × 10-⁷
f = 1.18 × 10¹⁵ Hz
Therefore, the frequency of an irradiation with wavelength of 2.54 × 10-⁷ metres is 1.18 × 10¹⁵ Hz.
