Exploring Curved Mirrors

What is a concave mirror?

• A concave mirror is a type of lens used in cameras.

• A concave mirror is a flat reflective surface.

• A concave mirror is a mirror with an inward-curved reflective surface.

• A concave mirror is a mirror with an outward-curved reflective surface.

How does a concave mirror form an image?

• A concave mirror forms an image by reflecting light rays that converge, creating real or virtual images based on the object's distance.

• A concave mirror scatters light rays, preventing image formation.

• A concave mirror only forms virtual images regardless of the object's distance.

• A concave mirror can only create images in complete darkness.

What are the characteristics of images formed by concave mirrors?

• Images formed are always virtual and cannot be inverted.

• Images are always larger than the object.

• Images formed by concave mirrors can be real or virtual, inverted or upright, and can vary in size depending on the object's position.

• Images are always real and upright.

List one application of concave mirrors in daily life.

• Bicycles

• Makeup mirrors

• Car headlights

• Solar panels

How does the focal point of a concave mirror differ from that of a convex mirror?

• The focal point of a concave mirror is real and in front, while that of a convex mirror is virtual and behind.

• The focal point of a concave mirror is virtual and behind, while that of a convex mirror is also virtual and behind.

• The focal point of a concave mirror is virtual and behind, while that of a convex mirror is real and in front.

• Both concave and convex mirrors have real focal points in front of the mirrors.

What is the significance of the principal axis in concave mirrors?

• The principal axis determines the color of the mirror.

• The principal axis is crucial for understanding image formation and measurement in concave mirrors.

• The principal axis is used to calculate the weight of the mirror.

• The principal axis is irrelevant to image clarity in concave mirrors.

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

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

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

What happens to the image when the object is placed at the focal point of a concave mirror?

• The image is formed at infinity and cannot be seen.

• The image is inverted and located at the center of curvature.

• The image is virtual and located behind the mirror.

• The image is formed at the focal point and is real.

Explain how concave mirrors are used in shaving mirrors.

• Concave mirrors absorb light to reduce glare while shaving.

• Concave mirrors are primarily used for lighting in bathrooms.

• Concave mirrors are used to create a flat reflection for shaving.

• Concave mirrors magnify the image of the face, providing better visibility for shaving.

What is the difference between real and virtual images in concave mirrors?

• Real images cannot be projected; virtual images can be projected.

• Real images are always upright; virtual images are always inverted.

• Real images are formed by convex mirrors; virtual images are formed by concave mirrors.

• Real images can be projected and are inverted; virtual images cannot be projected and are upright.
