Question Detail

PHY 104 Photo Electric Emission Objective Question

Question

For light, what is the relationship between momentum (p), Planck's constant (h), and wavelength (λ)?
Options
A p = hλ
B p = h/λ
Correct Answer
C p = c/λ
D p = E/c
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 15, under 'SUMMARY OF PHOTON PROPERTIES', states 'For light E = pc and c = λν', and then derives 'p = h/λ'.

Hint

Look at the summary of photon properties on page 15, specifically the relationship between momentum and wavelength for light.
