A light ray strikes a plane mirror at an angle of $28^{\circ}$ to the normal. If the light source is moved so that the angle of incidence increases by $34^{\circ}$, what is the new angle of reflection?

An electron passes through a magnetic field at right angles to the field at a velocity of $4.0 \times 10^{6} \mathrm{m} / \mathrm{s}$. The strength of the magnetic field is 0.50 T. What is the magnitude of the force acting on the electron?

An object is located 4.4 cm in front of a concave mirror with a 24.0-cm radius. Locate the image using the mirror equation.

Shiny spheres that are placed on pedestals on a lawn are convex mirrors. One such sphere has a diameter of 40.0 cm. A 12-cm-tall robin sits in a tree that is 1.5 m from the sphere. Where is the image of the robin and how tall is the image?

When you swipe a credit card, the machine sometimes fails to read the card. What can you do differently? $(a)$ Swipe the card more slowly so that the reader has more time to read the magnetic stripe. $(b)$ Swipe the card more quickly so that the induced emf is higher. $(c)$ Swipe the card more quickly so that the induced currents are reduced. $(d)$ Swipe the card more slowly so that the magnetic fields don't change so fast.

A cup sits 17 cm from a concave mirror. The image of the book appears 34 cm in front of the mirror. What are the magnification and orientation of the cup’s image? A. 0.5, inverted. B. 0.5, upright. C. 2.0, inverted. D. 2.0, upright.

A jeweler inspects a watch with a diameter of 3.0 cm by placing it 8.0 cm in front of a concave mirror of 12.0-cm focal length. a. Where will the image of the watch appear? b. What will be the diameter of the image?

Sunlight falls on a concave mirror and forms an image that is 3.0 cm from the mirror. An object that is 24 mm tall is placed 12.0 cm from the mirror. a. Sketch the ray diagram to show the location of the image. b. Use the mirror equation to calculate the image position. c. How tall is the image?

A 3.0-cm-tall object is 22.4 cm from a concave mirror. If the mirror has a radius of curvature of 34.0 cm, what are the image position and height?

How far does the image of a car appear behind a convex mirror, with a focal length of -6.0 m, when the car is 10.0 m from the mirror?

A dentist uses a small mirror with a radius of 40 mm to locate a cavity in a patient’s tooth. If the mirror is concave and is held 16 mm from the tooth, what is the magnification of the image?

A light ray strikes a flat, smooth, reflecting surface at an angle of $80^{\circ}$ to the normal. What is the angle that the reflected ray makes with the surface of the mirror?

The outside rearview mirrors of cars often carry the warning “Objects in the mirror are closer than they appear.” What kind of mirrors are these and what advantage do they have?

An object is 30.0 cm from a concave mirror of 15.0 cm focal length. The object is 1.8 cm tall. Use the mirror equation to find the image position. What is the image height?
