What does “Photon energy” actually mean in Modern Physics, and why does it matter for NEET?
light comes in packets of energy E = hf = hc/λ.
In simple words: light comes in packets of energy E = hf = hc/λ. Getting Photon energy clear matters because NEET questions on Modern Physics usually test this idea directly, not just a formula you memorised.
Key point
Photon energy
Common mistake
treating light purely as a wave when explaining the photoelectric effect.
Memory tip
higher frequency (bluer light) means more energetic photons.
