Exam 25: The Refl Ection of Light: Mirrors

A woman stands 2.0 m in front of a convex mirror and notices that her image height is 1/4 of her actual height.Determine the radius of curvature of the mirror.

An object is placed in front of a concave spherical mirror as shown below.The three rays 1,2,and 3,leave the top of the object and,after reflection,converge at a point on the top of the image.Ray 1 is parallel to the principal axis,ray 2 passes through F,and ray 3 passes through C. -Which one of the following groups of terms best describes the image?

Which one of the following statements concerning the image formed by a concave spherical mirror is true?

A concave mirror is found to focus parallel rays at a distance of 18 cm.Where is the image formed when an object is placed 6.0 cm in front of the mirror?

Which one of the following statements is not a characteristic of a plane mirror?

A convex mirror with a focal length of 58 cm is used to form an image that is 29 cm behind the mirror.What is the object distance?

An object with a height of 3.0-cm is placed 8.0 cm in front of a mirror.The virtual image is 4.0 cm further from the mirror when the mirror is concave than when it is planar. -Determine the focal length of the concave mirror.

A plane mirror is 6 ft tall.What is its focal length?

An object is placed 20.0 cm in front of a convex spherical mirror with radius of curvature 60.0 cm.Which one of the following phrases best describes the image?

Two mirrors are arranged as shown in the drawing.Light is incident from the right on the first mirror at an angle of 70°.The light reflects toward the second mirror and is reflected at angle .Determine the angle 11ec9dfd_8b1d_90b1_8d20_ffc56304147b_TB6393_11

Which one of the following statements concerning rays is false?

Which one of the following statements concerning a virtual image produced by a mirror is true?

Which one of the following phrases most accurately describes the term wave front?

A rubber ball is held 4.0 m above a concave spherical mirror with a radius of curvature of 1.5 m.At time equals zero,the ball is dropped from rest and falls along the principal axis of the mirror.How much time elapses before the ball and its image are at the same location?

Five balls labeled A,B,C,D,and E are placed in front of a plane mirror as shown in the figure.Which ball(s)will the observer,in the position shown,see reflected in the mirror?

A dime is placed in front of a concave mirror that has a radius of curvature R = 0.30 m.The image of the dime is inverted and three times the size of the dime.Determine the distance between the dime and the mirror.

A 0.127-m pencil is oriented perpendicular to the principal axis of a concave spherical mirror that has a radius of curvature of 0.300 m.What are the image distance and the image height if the pencil is 0.250 m from the mirror?

A convex mirror has a radius of curvature of 0.50 m.Where must an object be placed in front of the mirror such that the image is formed 0.15 m behind the mirror?

The view in the figure is from above a plane mirror suspended by a thread connected to the center of the mirror at point C.A scale is located 0.65 m (the distance from point C to point A)to the right of the center of the mirror.Initially,the plane of the mirror is parallel to the side of the scale;and the angle of incidence of a light ray which is directed at the center of the mirror is 30°.A small torque applied to the thread causes the mirror to turn 12° away from its initial position.The reflected ray then intersects the scale at point B.What is the distance from point A to point B on the scale?

A concave mirror in an amusement park has a radius of curvature of 4.0 m.A child stands in front of the mirror so that she appears 3.0 times taller than her actual height.If the image is upright,how far is she standing from the mirror?
