Four, 1.0m long plane mirrors are situated to form a box filled with air. A beam of light is sent out from one corner directed at a 30.0° angle from the vertical, as shown below. The beam of light then bounces around the interior of the box. a. Calculate the distance between the point of origin and the point where the beam first strikes wall I.

A ray of light strikes a polished surface at an angle of 37˚. What is thethe angle of reflection and location of the reflected ray?   A. 37.0˚ on the same side with the incident ray B. 37.0˚ on the other side of the normal line C. 53.0˚ on the same side with the incident ray D. 53.0˚ on the other side of the normal line

A ray of light is passed through a ruby and it hits a surface in contact with air (n = 1.000) at an angle of 45° with respect to the normal.  Use the table below to determine happens when it hits           the surface? What is the critical angle?   The ray refracts into the air at an angle of 45° with respect to the normal. The ray reflects back into the ruby at an angle of 45° with respect to the normal. The ray refracts at an angle of 90° with respect to the normal, along the surface. The ray is absorbed in the air. None of the above.

Q1. A ray of light (ray a) in air (index of refraction=1) strikes a flat piece of glass at an angle of p0 = 84° with respect to the normal, as shown in the figure. The index of refraction of the glass is 1.5. What is the angle 0 between the reflected ray (ray b) and refracted ray (ray c) rays?

Light in vacuum is incident on the surface of a slab of transparent material. In the vacuum the beam makes an angle of 31.1° with the normal to the surface, while in the slab it makes an angle of 22.0° with the normal. What is the index of refraction of the transparent material? Number i Units eTextbook and Media

Use the exact values you enter to make later calculations.A ray of light strikes a flat, 2.00-cm-thick block of glass (n = 1.96) at an angle of ? = 32.4° with respect to the normal (see figure below). A light ray incident on a glass block of thickness 2.00 cm is shown. The ray travels down and to the right and is incident to the top of the block at an angle ? to the normal of the surface. The ray inside the block moves down and to the right but at a steeper slope than the incident ray. It is incident on the bottom surface of the block and exits moving down and to the right, in the same direction as the incident ray. A dashed line extends from the original path of the ray down in the block and is shown to be a distance d from the ray that exits the glass block. (a) Find the angle of refraction at the top surface and the angle of incidence at the bottom surface. °(b) Find the refracted angle at the bottom surface. °(c) Find the lateral distance d by which the light beam is shifted. cm(d)…

A ray of light is pointed at the surface of a block of fused quartz at an angle of 30.0° with respect to the normal (a line perpendicular to the surface at the spot where the ray hits the block). Part of the light is reflected and the rest refracted. What is the angle (in degrees) between the reflected and refracted rays? O
