Chapter 35, Problem 8P
Why is the following situation impossible? At a blind corner in an outdoor shopping mall, a convex mirror is mounted so pedestrians can see around the corner before arriving there and bumping into someone traveling in the perpendicular direction. The installers of the mirror failed to take into account the position of the Sun, and the mirror focuses the Sun’s rays on a nearby bush and sets it on fire.

Why is the following situation impossible?

The installers of the mirror failed to take into account the position of the Sun, and the mirror focuses the Sun’s rays on a nearby bush and sets it on fire.
A man stands 1.00 m in front of a plane mirror. His eyes are 1.75 m above the ground. The top of the mirror is level with his eyes. How long must the mirror be in order for him to see his shoes in the mirror, assuming that he is standing with both feet firmly on the floor? Does his distance from the mirror matter?
Why 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.

- Under what circumstances will an image be located at the focal point of a spherical lens or mirror?arrow_forwardAn observer to the right of the mirror-lens combination shown in Figure P36.89 (not to scale) sees two real images that are the same size and in the same location. One image is upright, and the other is inverted. Both images are 1.50 times larger than the object. The lens has a focal length of 10.0 cm. The lens and mirror are separated by 40.0 cm. Determine the focal length of the mirror.arrow_forwardA small insect starts walking away from a concave spherical mirror along its central axis. Which statement is true?arrow_forward
- A dentist uses a concave mirror to send light into his patients’ mouths. If a parallel beam of light supplied by a lamp is to be concentrated at a distance 2.5 cm from the mirror, what should be the radius of curvature?

The drawings show two arrows, A and B, that are located in front of a plane mirror. A person at point P is viewing the image of each arrow. Which images can be seen in their entirety? Determine your answers by drawing a ray from the head and foot of each arrow that reflects from the mirror according to the law of reflection and reaches point P. Only if both rays reach point P after reflection can the image of that arrow be seen in its entirety. (Select all that apply.)

How far should you place the object from the mirror so that the lateral magnification produced by the mirror will be +2.5? 30 cm 36 cm 18 cm O 42 cm O 24 cmarrow_forwardA 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?arrow_forwardA small mirror is attached to a vertical wall, and it hangs a distance of 1.87 m above the floor. The mirror is facing due east, and a ray of sunlight strikes the mirror early in the morning and then again later in the morning. The incident and reflected rays lie in a plane that is perpendicular to both the wall and the floor. Early in the morning, the reflected ray strikes the floor at a distance of 3.14 m from the base of the wall. Later on in the morning, the ray is observed to strike the floor at a distance of 1.27 m from the wall. The earth rotates at a rate of 15.0˚ per hour. How much time (in hours) has elapsed between the two observations?arrow_forward
