Question

which of the following statement is not correct?
-a light is a kind of electromagnetic wave

b light is a kind of probability wave

c a photon is the same as a high - speed proton

d the energy of a photon is determined by its frequency

e the spread of light in air is discontinuous

Explanation:

• Option a: Light is an electromagnetic wave (correct, from electromagnetism theory).
• Option b: In quantum mechanics, light (as a photon) can be described with probability wave concepts (correct).
• Option c: A photon is a quantum of electromagnetic radiation, while a proton is a subatomic particle with mass and charge; they are fundamentally different (incorrect statement).
• Option d: Photon energy is given by \( E = h

u \) (where \( h \) is Planck's constant, \(
u \) is frequency), so energy depends on frequency (correct).

• Option e: Light propagation in air (as photons) is discontinuous in terms of energy transfer (quantized), though the wave - like propagation seems continuous macroscopically (correct in quantum context).

Answer:

c. A photon is the same as a high - speed proton
