MHT CET · Physics · Electromagnetic Waves
An electromagnetic wave of wavelength ' \(\lambda\) ' is incident on a photosensitive surface of negligible work function. If the photoelectrons emitted from this surface have the de-Broglie wavelength ' \(\lambda_{1}{ }^{\prime}\) then
- A \(\lambda \propto \frac{1}{\lambda_{1}}\)
- B \(\lambda \propto \lambda_{1}\)
- C \(\lambda \propto \lambda_{1}^{2}\)
- D \(\lambda \propto \frac{1}{\lambda_{1}^{2}}\)
