A metal alloy of unknown composition was bombarded with 186 nm photons to determine its photoelectric properties. Electrons photo-ejected from this alloy had a velocity of 8.00 × 10⁵ m/s. What is the work function, Φ, of this alloy in e
Compton effect
The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.
Recoil Velocity
The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.
A metal alloy of unknown composition was bombarded with 186 nm photons to determine its photoelectric properties. Electrons photo-ejected from this alloy had a velocity of 8.00 × 10⁵ m/s. What is the work function, Φ, of this alloy in eV? (1 eV = 1.60 × 10⁻¹⁹ J, the mass of an electron is 9.109 x 10⁻³¹ kg, and Planck's constant is 6.626 x 10⁻³⁴ Js.)
