what is the formula for reflection speed. Distance traversed by the sound wave vt. As the distance that needs to calculated of sound should include the reflection of sound going to and fro from the surface thus 2d distance 2 times.

As the distance that needs to calculated of sound should include the reflection of sound going to and fro from the surface thus 2d distance 2 times. For p-polarized light we have R r 12p 2 where r 12p is the Fresnel reflection coefficient for p-polarization. Wavelength of monochromatic light l 589 nm Speed of light c 3 10 8 m s Refractive index m 1.
Distance traversed by the sound wave vt.
In coaxial cable the speed of an electrical signal is about 23 of this or about 8 inns. The speed of light in the glass. Time taken for hearing the echo t 3 s. Find out the refractive index of the medium such that the speed of light in the medium is 2 108 ms.
