When the radiation of light is passed through a prism, it undergoes __________?
Correct answer: D. refraction
- A. reflection
- B. interference
- C. diffraction
- D. refraction
Explanation
When light enters a prism, it changes speed at the boundary between air and glass and bends, which is refraction. Different wavelengths bend by different amounts, producing dispersion as well. Students may choose diffraction because light can spread, but diffraction occurs when light passes around edges or through narrow openings.

About Planck's Quantum Theory
Planck's quantum theory states that energy is emitted or absorbed in discrete packets called quanta, with each packet having energy E = hν. It covers the meaning of Planck's constant, the relationship between frequency and wavelength, and how quantisation differs from the classical continuous model of energy.
