Question

The frequency associated with photon of radiation having a wavelength of $6000A^0$ is

• A. 5 X 10¹⁴ Hz
• B. 5 X 10¹⁰ Hz
• C. 2 X 10¹⁴ Hz
• D. 5 X 10¹⁵ Hz

Answer 1

The correct option is A

5 X 10¹⁴ Hz

$v=\frac{c}{\lambda }=\frac{3\times {10}^{10}}{6\times {10}^{-5}}=5\times {10}^{14}Hz$
