Q1.

A concave mirror has a focal length of 20 cm. What is the position (in cm) of the resulting image if the image is inverted and 2.5 times smaller than the object?

Q2.

A convex mirror has a focal length of 20 cm. What is the position of the image (in cm), if the image is upright and 2.6 times smaller than the object? (For convex mirror, f is negative, and since the image is behind the mirror, q is also negative number).

Q3.

An object 4 cm high is placed 29 cm in front of a convex mirror with a focal length of 20 cm. What is the image position (in cm)? (Use: f = negative number, p is positive number, and q will be a negative number, since it is behind the mirror)). Use the correct sign in the answer.

Q4.

An object is placed 30 cm in front of a concave mirror with a 7-cm focal length. Determine the image location (in cm).

Q5.

An object 20-cm high is placed 50 cm in front of a lens whose focal length is 5.0 cm. Where will the image be located (in cm)?
