Challenge Problems
Push your limits with challenges.
Question 1
A metal has a work function of 3 eV. If light with a frequency of 8 x 10^14 Hz hits its surface, calculate whether electrons will be emitted and determine their maximum kinetic energy.
💡 Hint: Consider using Planck's constant to derive energy.
Question 2
Calculate the de Broglie wavelength of a proton moving at 1 x 10^7 m/s.
💡 Hint: Remember h = 6.63 x 10^-34 J·s is Planck's constant!
