Question

In \[p=\frac{h}{\lambda}\], what does \[\lambda\] represent?

Options

• Maximum kinetic energy of emitted electron

• Energy of one photon

• Wavelength of radiation

• Frequency of radiation

Answer 1

The symbol \[\lambda\] represents the wavelength of radiation. Photon momentum is inversely related to wavelength through \[p=\frac{h}{\lambda}\].
