A light beam shines through air and then strikes a mirror, making an angle theta = 39.0 degrees with respect to the vertical, as shown. The reflected beam then strikes a pane of glass of thickness h = 1.68 cm, located a distance y= 48.5 cm from the mirror, and then exits the glass pane at the bottom, a horizontal distance x cm away from where it struck the mirror. What is the value of x?
What must be the minimum value of the index of refraction of the prism shown in Fig. 19.16 a in order that light betotally reflected where indicated? Is the index of refraction of mosttypes of glass greater than this value?
A light ray is incident normally to the long face (the hypotenuse)of a 45°–45°–90° prism surrounded by air, as shownin Figure 22.26b. Calculate the minimum index of refractionof the prism for which the ray will totally internally reflect ateach of the two sides making the right angle.
Suppose Figure 25.54 represents a ray of light going from air through crown glass into waist, such as going into a fish tank. Calculate the amount the ray is displaced by the glass (x) , given mat me incident angle is 40.0° and the glass is 1.00 cm thick.
Repeat the previous problem for glasses that are 1.75 cm from the eyes.
Check Your Understanding In the preceding example. how much distance inside the block of flint glass would the red and the violet rays have to progress before they are separated b 1.0 mm?
Will 1igt change direction toward or away from the perpendicular when it goes from air to water? Water to glass? Glass to air?
A ray of light, emitted beneath the surface of an unknown liquid with air above it, undergoes total internal reflection as shown in Figure 25.55. What is the index of retraction for the liquid and its likely identification? Figure 25.55 A tight ray inside a liquid strikes the surface at the critical angle and undergoes total internal reflection.
A spherical mirror is made by silver-coating half of the inside of a sphere of radius R = 20 cm. A light ray moves horizontally 5.0 cm above the axis of the mirror as in Fig.19.23. When reflected from the mirror, how far from the mirror does the ray cross the axis? You will need to use some trigonometry and geometry to solve this problem.
A ray of light travelling in air enters obliquely into water. Does the light ray bends towards the normal or away from the normal? Why?
As shown in the figure, a light beam travels from air, through olive oil, and then into water. If the angle of refraction ?2for the light in the olive oil is 33.4°, determine the angle of incidence ?1in air and the angle of refraction ?3in water. The index of refraction for olive oil is 1.47.?1 = °?3 = °
A light ray traveling in air is incident on one face of a rightangleprism with index of refraction n = 1.50, as shown inFigure P22.54, and the ray follows the path shown in the figure.Assuming Θ = 60.0° and the base of the prism is mirrored,determine the angle Φ made by the outgoing ray with the normalto the right face of the prism.
