d, d; In the picture above, you know the distance from the lens to the object, d, = 7cm, and the distance from the mirror to the image, d; %3D = 4.6cm. The position of the focal point must be at i cm. (Record your answer to two decimal places.)

For each assume the focal length is 10 cm and height is 5cm. Determine the distance and calculate image distance,image height and magnification

The lens and mirror in the figure below are separated by 1.00 m and have focal lengths of +79.7 cm and −49.3 cm, respectively. If an object is placed 1.00 m to the left of the lens, where will the final image be located? q3 = ?cm   Determine the overall magnification ???

A glass sphere (n = 1.50) with a radius of 16.0 cm has a tiny air bubble 4.30 cm above its center. The sphere is viewed looking down along the extended radius containing the bubble. What is the apparent depth of the bubble below the surface of the sphere? 7.936 Apply the equation relating the object distance, image distance, and radius of curvature for a spherical refracting surface. cm Need Help?
