Two sources of light are said to be coherent when both give out light waves of same:
Phase difference between two coherent sources should be:
Coherent sources can be created by the division of:
In a Fresnel’s biprism experiment, the two coherent sources are obtained by:
A 60.0 kHz transmitter sends an EM wave to a receiver 21 km away. The signal also travels to the receiver by another path where it reflects from a helicopter. Assume that there is a 180o phase shift when the wave is reflected. This situation will give ________.
Light of wavelength λ in vacuum enters a medium of refractive index μ. Two points in this medium, lying along the path of this light, are at a distance x apart. The phase difference between these points is
Which of the following is not essential for two sources of light in Young’s double slit experiment to produce a sustained interference?
Which of the following is not an example of coherent source produced by the division of wavefront?
