A light ray in a vacuum is an incident on an equilateral triangular prism. It makes an angle of 13.2 degrees with the normal of the prism's surface. It makes an angle of 12.4 degrees with the normal after entering the prism. What is the angle it makes with the far side's normal after exiting the prism?
A light beam is incident upon a mirror that is held horizontally. The angle that the light beam makes with the normal line is 50°. But then, the mirror is tilted at an angle of 30° above the horizontal without changing the direction of the light beam. What is the angle of incidence in degrees?
As shown in the figure, a ray of light strikes a plane mirror with some incident angle. The mirror is now rotated by an angle of ? = 19.0° about an axis through the point where N1 contacts the mirror, without altering the incident ray. The new position is shown by the line M2.
(a) Determine the angle through which the reflected ray rotates if the incident angle is 40.0°.°
(b) Determine the angle through which the reflected ray rotates if the incident angle is 50.0°.°

- (i) An object is plated at a position p f from a concave mirror as shown in Figure CQ39.12a, where f is the focal length of the mirror. In a finite time interval, the object is moved to the right to a position at the focal point F of the mirror. Show that the image of the object moves at a speed greater than the speed of light. (ii) A laser pointer is suspended in a horizontal plane and set into rapid rotation as shown in Figure CQ39 12b.

- A plane mirror and a concave mirror (f = 6.70 cm) are facing each other and are separated by a distance of 20.0 cm. An object is placed between the mirrors and is 10.0 cm from each mirror.

Specify this distance relative to the concave mirror. Number i C Object F Unitsarrow_forwardWhy is the following situation impossible? The perpendicular distance of a lightbulb from a large plane mirror is twice the perpendicular distance of a person from the mirror. Light from the lightbulb reaches the person by two paths: (1) it travels to the mirror and reflects from the mirror to the person,and (2) it travels directly to the person without reflecting off the mirror. The total distance traveled by the light in the first case is 3.10 times the distance traveled by the light in the second case.arrow_forwardAs shown in the figure, a ray of light strikes a plane mirror with some incident angle.
