If frequency of a photon is 6 10¹⁴ ~Hz , then find its wavelength. [Take, speed of light, c =3 10^8 ~m / s ]

Options

  1. A500 Å
  2. B500 nm
  3. C200 Å
  4. D200 nm

Correct answer

B. 500 nm

Step-by-step solution

Given, Frequency of photon (v)=6 10¹⁴ ~Hz Speed of light ( c )=3 10^8 ~m / s Wavelength of photon = c v = 3 10^8 6 10¹⁴ =0.5 10⁻⁶=500 10⁻⁹=500 ~nm
