Question

the wavelength range of the visible spectrum extends from violet (400nm) to red (750nm). express these wavelength to frequencies (Hz). (1nm=10^-9m)​

Answer 1

Answer:

we can use

velocity=lambda * frequency

here.

as velocity will be speed of light that is 3*10^8 m/s

and lambda are the wavelengths which are given. So frequencies can be calculated

Answer 2
