Question

Please answer part C and D, Using the diagram in the first photo.

The ray diagram at right represents a periodic water wave at the boundary between two different media (i.e., two regions of different Reg depth in a large tank of water). The wave is generated by a dowel Reg moving back and forth at a steady rate. a. Does the propagation speed of the transmitted wave (in region 2) depend on the propagation speed of the incident wave (in region 1)? Explain. does not depend on regien Speed d pro pagatum s dependent on the index

Explanation / Answer

Here , as the beam moves towards the normal

the index of refraction of first medium will be higher than the index of refraction

c)

the frequency will be same as frequency does not change in refraction

--

propagation speed of the incident wave will decrease

the index of refraction of first medium will be higher than the index of refraction
--

the wavelength of the incident wave will decrease.

the index of refraction of first medium will be higher than the index of refraction

-------

Yes , it is possible if the refractive index of both media is same

d)

Yes , it is possible

the relation between i and r is

n1 * sin(i) = n2 * sin(r)

----------

yes it is possible if we change the refractive index of either media
