Question
The wave nature of light is demonstrated by which of the following ?*1 pointThe photoelectric effectDiffractionColourThe speed of light
Solution
The wave nature of light is demonstrated by Diffraction.
Here's why:
-
The Photoelectric Effect: This actually demonstrates the particle nature of light (photons), not its wave nature.
-
Diffraction: This is the bending of light waves around obstacles or the spreading of light waves after they pass through a narrow opening. This phenomenon can only be explained if light is considered as a wave.
-
Colour: While colour is a property of light, it doesn't specifically demonstrate the wave nature of light. It's more related to the frequency of the light wave.
-
The Speed of Light: This is a constant (in a vacuum) and while it's an important property of light, it doesn't specifically demonstrate the wave nature of light.
So, the correct answer is Diffraction.
