Intro to Optics

Convex Mirrors produce...

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

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 rays and cannot be projected on a screen

• is produced by real rays and can be projected on a screen

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

Mirrors that bulge out are called:

• Concave mirrors
• Convex mirrors

Which picture represents what happens when light travels through a CONVERGING lens?

• A- left picture

• B - Right picture
