Question

Name any two experimental phenomena that proves light has particle nature

Answer 1

Answer:

Light is defined as a transverse electromagnetic wave. Due to this nature, light can travel through a vacuum. Earlier studies were conducted based on diffraction and interference phenomenon which showed light to be a sort of disturbance.

However, the true transversal nature of light waves was proved only by the Polarization phenomenon. This phenomenon helps to specify the geometrical orientation of the oscillations.

Answer 2

Albert Einstein Explained This

Explanation:

Albert Einstein explained this "photoelectric" effect by proposing that light – thought to only be a wave – is also a stream of particles. Even though a variety ofexperiments have successfully observed both theparticle- and wave-like behaviors of light, they have never been able to observe both at the same time.
