Question

What is the wavelength of a photon of EMR with a frequency of 2.43x10^16 Hz?7.59x1024 m1.23x10-8 m8.10x107 Hz1.23x1024 m

Answer 1

Given

The frequency is

`n=2.43*10^(16)Hz`

To find

The corresponding wavelength

Step-by-step explanation

We know the velocity of a photon of EMR is same as the velocity of light

Thus,

`\begin{gathered} v=n\lambda \\ \Rightarrow\lambda=(3*10^8)/(2.43*10^(16)) \\ \Rightarrow\lambda=1.23*10^(-8)m \end{gathered}`

Conclusion

The required wavelength is

`1.23*10^(-8)m`
