Which of the following shows the particle nature of light?
Which of the following shows the particle nature of light?
The correct option is D Photoelectric effect
The explanation for correct options.
Photoelectric effect:
When a material absorbs electromagnetic radiation, electrically charged particles are released from or within it, resulting in the photoelectric effect. The effect is frequently defined as the ejection of electrons from a metal plate when exposed to light.
Hence, "Option (D)" is the correct option.
The explanation for incorrect options
For option (A) Refraction:
- When a light wave is an incident at an angle away from the normal, it passes through a boundary from one medium into another, and the velocity of the light changes.
- The bending of light when a light ray travels at an angle into a different medium with a different refractive index, this occurs.
- When the intensity of a refracted ray is less than that of an incident ray, refraction occurs.
- When a ray of light deviates from its normal path, it is refracted.
For option (B) Interference:
Interference is defined as the phenomenon of two or more waves of the same frequency emitted by coherent sources superimposing on each other. so that the sum of the amplitudes of the individual waves equals the resultant wave.
For option (C) Polarization :
Polarization (also polarisation) is a property of transverse waves that specifies their geometrical orientation. The oscillation direction in a transverse wave is perpendicular to the wave's motion direction.
Hence, "Option (D)" is the correct option.
