Light is incident on the left face of an isosceles prism; with an apex angle of 49o, such that the light exiting the right face is parallel to its surface.
what is the index of refraction of the prism, if the angle of incidence on the left face side is 19o to the normal of the face? light is incident towards the apex.

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
