The frequency of the ultraviolet light given that its wavelength is 100 nm is 3×10¹⁵ Hz
Data obtained from the question
- Wavelength (λ) = 100 nm = 100×10¯⁹ m
- Velocity of light (v) = 3×10⁸ m/s
- Frequency (f) =?
How to determine the frequency of the light
The frequency of the light can obtain as illustrated below:
v = λf
3×10⁸ = 100×10¯⁹ × f
Divide both side by 100×10¯⁹
f = 3×10⁸ / 100×10¯⁹
f = 3×10¹⁵ Hz
