Question

Calculate the frequency of yellow light of wavelength
550 nm. The speed of light is 3 x 100000000 m/s​

Answer 1

Answer:

As we know that;

c = f × l. ....(1)

where, c = speed of light

f = frequency of light

l = wavelength of light

Now, from (1)-

wavelength, l = c/f

or, l = 3×10^8/550× 10^-9

or, l = 0.5 × 10^15 m
