Exploring Mirrors and Lenses

What is the path of light rays when they strike a concave mirror?

• Light rays diverge away from the mirror after reflecting.

• Light rays converge at the focal point after reflecting off a concave mirror.

• Light rays reflect parallel to each other without converging.

• Light rays are absorbed by the concave mirror.

Draw a ray diagram for an object placed beyond the center of curvature of a concave mirror.

• The ray diagram shows a virtual, inverted, and smaller image formed at the center of curvature.

• The ray diagram shows a real, inverted, and larger image formed at the focal point.

• The ray diagram shows a virtual, upright, and larger image formed beyond the center of curvature.

• The ray diagram shows a real, inverted, and smaller image formed between the focal point and the center of curvature.

What type of image is formed by a concave mirror when the object is placed between the focal point and the mirror?

• The image is virtual, upright, and enlarged.

• The image is real, inverted, and reduced.

• The image is virtual, inverted, and reduced.

• The image is real, upright, and enlarged.

Describe the characteristics of the image formed by a concave mirror when the object is at the focal point.

• The image is virtual, upright, and located behind the mirror.

• The image is real, upright, and located at the focal point.

• The image is virtual, inverted, and located behind the mirror.

• The image is real, inverted, and located in front of the mirror.

What are the main characteristics of a convex lens?

• A convex lens can only produce real images.

• A convex lens diverges light and has a negative focal length.

• A convex lens has a flat surface and does not bend light.

• A convex lens converges light, has a positive focal length, and can produce both real and virtual images.

How does a convex lens affect the direction of light rays passing through it?

• A convex lens has no effect on the direction of light rays.

• A convex lens converges light rays towards a focal point.

• A convex lens reflects light rays instead of refracting them.

• A convex lens diverges light rays away from a focal point.

What type of image is formed by a convex lens when the object is placed beyond the focal point?

• A real and inverted image.

• An enlarged and upright image.

• A blurred and distorted image.

• A virtual and upright image.

List the characteristics of the image formed by a convex lens when the object is placed between the focal point and the lens.

• The image is real, upright, and larger than the object.

• The image is virtual, inverted, and the same size as the object.

• The image is real, inverted, and smaller than the object.

• The image is virtual, upright, and larger than the object.

What are some common applications of concave mirrors?

• Convex mirrors for security

• Lenses in cameras

• Common applications of concave mirrors include shaving mirrors, makeup mirrors, telescopes, and vehicle headlights.

• Flat mirrors in bathrooms

How are concave mirrors used in telescopes?

• Concave mirrors absorb light to enhance visibility in telescopes.

• Concave mirrors scatter light to create images in telescopes.

• Concave mirrors reflect light away from the telescope to reduce glare.

• Concave mirrors focus light to create magnified images in telescopes.
