Question

Visible light travels at a speed 3. 0 × 108 of m/s. If red light has a wavelength of 6. 5 × 10–7 m, what the frequency of this light?.

Answer 1

4.6 x 10^14 hz

Step-by-step explanation:

frequency = speed / wavelength

speed : 3.0 x 10^8

wavelength : 6.5 x 10^-7

frequency = 3.0 x 10^8 / 6.5 x 10^-7 = 4.6 x 10^14
