Understanding Spherical Mirrors

What is a spherical mirror?

• A mirror that reflects light in a straight line.

• A mirror that is always circular in shape.

• A spherical mirror is a mirror with a curved surface that is part of a sphere.

• A flat mirror with a reflective surface.

What are the two types of spherical mirrors?

• Reflective and Refractive

• Plane and Spherical

• Concave and Convex

• Flat and Curved

Define the focal point of a spherical mirror.

• The focal point is the center of the mirror.

• The focal point is the point where light rays are emitted from the mirror.

• The focal point is where light rays are absorbed by the mirror.

• The focal point of a spherical mirror is the point where parallel rays of light converge or appear to diverge after reflection.

What is the difference between concave and convex mirrors?

• Concave mirrors diverge light and provide a wider field of view, while convex mirrors focus light and magnify images.

• Concave mirrors are flat and do not reflect light, while convex mirrors are spherical and focus light.

• Concave mirrors provide a wider field of view, while convex mirrors focus light and create smaller images.

• Concave mirrors focus light and magnify images, while convex mirrors diverge light and provide a wider field of view.

How does a concave mirror form an image?

• A concave mirror forms an image by bending light rays to diverge from a focal point.

• A concave mirror forms an image by scattering light rays away from a focal point.

• A concave mirror forms an image by absorbing all incoming light rays.

• A concave mirror forms an image by reflecting light rays to converge at a focal point.

What is the mirror formula for spherical mirrors?

• 1/v = 1/f - 1/u

• 1/f = 1/v + 1/u

• f = uv

• 1/f = v + u

Explain the significance of the center of curvature.

• The center of curvature is the point where the curve intersects the x-axis.

• The center of curvature is irrelevant to the shape of a curve.

• The center of curvature is the midpoint of a line segment.

• The center of curvature is the point that defines the radius of curvature of a curve, indicating how sharply it bends.

What is the relationship between object distance and image distance in spherical mirrors?

• The image distance is always equal to the object distance.

• The image distance is independent of the object distance.

• The relationship is defined by the equation: f = uv.

• The relationship is given by the mirror formula: 1/f = 1/v + 1/u.

How does the curvature of a mirror affect its focal length?

• The curvature of a mirror has no effect on its focal length.

• The more curved the mirror, the longer its focal length.

• A flat mirror has a shorter focal length than a curved mirror.

• The more curved the mirror, the shorter its focal length.

What are some practical applications of spherical mirrors?

• Spherical mirrors are used in telescopes for deep space observation.

• Concave mirrors are used in solar panels to focus sunlight.

• Convex mirrors are used in car side mirrors to reduce blind spots.

• Concave mirrors are used in shaving mirrors and headlights; convex mirrors are used for security in parking lots.
