Question

Calculate the frequency of radiation having wavelength of 5000 A°​

Answer 1

Answer:

1.998616386E-10Hz ( converted from m/s to Hz)

Explanation:

c = λ * v

Given wavelength = 5000Α⁰

c = speed of light 3x10⁸m/s

5000 Armstrong = 5 x 10-8 Meters

v = c/λ

  =3.0 x 10⁸/5 x 10⁻⁸

  = 3.0 x 10⁸ x 5 x 10⁸

  = 15 x 10¹⁶ m/s

  =1.998616386E-10Hz
