The energy, \( E \), of a photon can be expressed as \( E = hf \) where \( f \) is the frequency and \( h \) is Planck's constant. The dimensions of \( h \) are the same as that of
- A. linear momentum
- B. angular momentum ✓
- C. displacement
- D. torque
Correct Answer: B. angular momentum
Explanation
Planck's constant has the dimensions of \( [ML^2T^{-1}] \), which are the same as the dimensions for angular momentum.
