Optics

Convex Mirrors produce...

• only virtual images
• virtual or real images
• only real images
• inverted images

If a candle is placed at 2f in front of a converging lens, the image

• will appear at f on the opposite side of the lens
• the image will appear at 2f on the opposite side of the lens
• the image will appear between f and 2f on the opposite side of the lens
• the image will not appear

Concave mirrors will produce...

• Real, erect images
• Virtual, inverted images
• Real, inverted images
• no images form

If an object is placed at f in front of a concave mirror...

• the image forms at f
• the image forms at 2f
• the image forms at 3f
• no image forms

An erect image which is smaller than the object forms...

• behind a concave mirror
• in front of a convex lens
• behind a convex mirror
• in front of a concave mirror

An image with a magnification of -1/2...

• is produced behind a convex mirror
• is produced by a convex lens on the side opposite the object
• is produced by a concave lens on the same side as the object
• is produced behind a concave mirror

An image with magnification of M = -3...

• is formed by a convex mirror, beyond 3f and it is virtual
• is formed by a concave lens, between f and 2f and it is real
• is formed by a convex lens between f and 2f and it is virtual
• is formed by a concave mirror beyond 3f and it is real

An incident ray that is parallel to the principal axis...

• will reflect parallel to the principal axis
• will refract through the focal point
• will reflect through the center of curvature
• will continue along the same path through the lens

a ray that reflects through f

• is produced by a ray that is incident to the lens and is parallel the the principal axis
• is produced by a ray that is incident to the mirror and is parallel the the principal axis
• is produced by a ray that is incident to the mirror and passes through the focal point
• is incident to the lens and passes through the center of curvature

a real image...

• is produced by virtual rays and can be projected on a screen
• is produced by real rays and cannot be projected on a screen
• is produced by virtual images and cannot be projected on a screen
• is produced by real rays and can be projected on a screen
