Related Optics MCQ with Answers
Answer is:
locus of all adjacent points at which the phase of vibration of a physical quantity associated with the wave is the same
Explanation:
A wave front is a surface containing points affected in the same way by a wave at a given time.
Answer is:
line along the direction of travel of the wave
Explanation:
In optics a?ray?is an idealized model of?light, obtained by choosing a line that is perpendicular to the wavefronts of the actual?light, and that points in the direction of energy flow.
Answer is:
each point on a wave front is a source of secondary waves
Explanation:
The Huygens-Fresnel principle states that every point on a wavefront is a source of wavelets. These wavelets spread out in the forward direction, at the same speed as the source wave. The new wavefront is a line tangent to all of the wavelets.
Answer is:
new wave front is the forward envelope of the secondary waves
Explanation:
The Huygens-Fresnel principle states that every point on a wavefront is a source of wavelets. These wavelets spread out in the forward direction, at the same speed as the source wave. The new wavefront is a line tangent to all of the wavelets.
