The frequency of violet light is 7.5 xx ...

The frequency of violet light is `7.5 xx 10^(14)` Hz. Find its wavelength in (i) nm, (ii) Å. Speed of light `c = 3 xx 10^(8) m s^(-1)`

Text Solution

AI Generated Solution

To find the wavelength of violet light given its frequency, we can use the formula that relates the speed of light (c), frequency (f), and wavelength (λ): \[ \lambda = \frac{c}{f} \] Where: - \( c \) is the speed of light, approximately \( 3 \times 10^8 \, \text{m/s} \) ...
