Ray Diagram Law. Unlike reflection refraction also depends on the media through which the light rays are travelling. In this tutorial we review the most important topics in the plane flat mirrors in physics.
The spacing of the crystal planes d. For example if a light ray hits a. The crystal orientation defined by the angle θ.
You do a diagram and any ray parallel to the x axis is bounced thro the focal point that is the brown line as for your second part none of us better answer there are two conventions rip nccc real is positive or new cartesian coordinate convention and they give opposite answers neg means imaginary image or.
The spacing of the crystal planes d. I calculate the angle of incidence. The law of refraction snells law like with reflection refraction also involves the angles that the incident ray and the refracted ray make with the normal to the surface at the point of refraction. A angle of incidence.
