Find the wavelength (in nm) of a photon whose energy is 6.70 × 10-19 J.

The maximum wavelength that an electromagnetic wave can have and still eject electrons from a metal surface is 507 nm. What is the work function W0 of this metal? Express your answer in electron volts.

In the Compton effect, an X-ray photon of wavelength 0.16 nm is incident on a stationary electron. Upon collision with the electron, the scattered X-ray photon continues to travel in the same direction as the incident photon. What is the wavelength λ' of the scattered photon?

A particle (m = 3.4 × 10-28 kg) starting from rest, experiences an acceleration of 2.4 × 107 m/s2 for 5.0 s. What is its de Broglie wavelength λ at the end of this period?
