Diffraction of Light
What is meant by the diffraction of light?
The phenomenon of bending of light around the edge of the particle is called the diffraction of light.
What is the essential condition for the diffraction of light to occur?
The essential condition for the diffraction of light to occur is the length of the obstacle must be comparable to the wavelength of light.
What is the Phase Difference?
The difference in the phase angle of the two waves is called the phase difference whereas the difference in the path covered by the two waves is called the path difference.,
What is the Condition for Constructive Interference?
If the phase difference between two certain waves is an even multiple of π then constructive interference occurs, also path difference must be an integral multiple of the wavelength.
What is the condition for destructive interference?
If the phase difference between two certain waves is an odd multiple of π then destructive interference occurs.
What is Total Internal Reflection?
When a light ray goes from a denser medium to a rarer medium at an angle greater than the critical angle it gets reflected instead of being refracted this phenomenon is called Total Internal Reflection.
What is the Formula for the Width of the Central Maxima?
The Formula for the Width of the Central Maxima is,
θ = 2λa
Diffraction of light
Diffraction is a phenomenon shown by light. When the wave of light interacts with the particle in the atmosphere it bends at the corners and scatters in the area to illuminate the whole area, this phenomenon is called the Diffraction of light. It is a property of light which is used to explain various phenomena observed in our daily life.
