Question

A concave mirror has a focal length of 52.7 cm. (a) What is its radius of curvature? cm ? (b) Locate the image when the object distance is 100 cm. (Indicate the side of the mirror with the sign of your answer.) cm ? Describe the properties of the image when the object distance is 100 cm. (Select ALL that apply.) real virtual upright inverted (c) Locate the image when the object distance is 10.0 cm. (Indicate the side of the mirror with the sign of your answer.) cm ? Describe the properties of the image when the object distance is 10.0 cm. (Select ALL that apply.) real virtual upright inverted

Explanation / Answer

a) radius of curvature r=2*f=2*52.7=105.4 cm

b) 1 / u + 1 / v = 1 / f
1 / 100 + 1 / v = 1 / (52)
v = 108.33 cm.
Image distance 11.9 cm and Image is real and inverted.

c) 1 / u + 1 / v = 1 / f
1 / 10 + 1 / v = 1 / (52)
v = - 12.3 cm.
Image distance =12.3 cm and Image is virtual and Upright.
