Challenge Problems
Push your limits with challenges.
Question 1
Explain how the photoelectric effect supports the particle nature of light.
💡 Hint: Consider how traditional wave theories couldn't explain electron emission based on frequency.
Question 2
Given light of frequency 5 × 10^14 Hz and a metal with a work function of 3.12 × 10^-19 J, calculate whether electrons will be emitted.
💡 Hint: Use the values given and apply the photoelectric equation to determine the outcome.
