Question

6. Yellow light emitted from sodium vapour lamp has

wavelength (λ) of 580 nm. Calculate the frequency given

c =3.8X108 m s-
​

Answer 1

$\huge\boxed{Answer}$

The wavelength of yellow light is 580nm = 580×10 -9m

The frequency of yellow light,

ν= λ/c = 580×10 −9m3.0×10 8m/s=5.17×10 10¹⁴m/s.
