An object reflected in a huge convex mirror of radius 2.2 m appears to have a height of 48.5 cm. What is the height of the object if it is located 4.4 m from the surface of the mirror? Provide your answer in meters, with the precision of three places after the decimal. Keep in mind the notation should reflect the type of the image and its orientation. Consider a semicircular disc of glass with an index of refraction n=1.6 and a screen placed 22 cm from the flat side of the disc. Determine the incident angle 0 for which the beam of light in the figure below will hit the point located d=10.5 cm above the principal axis of the disc. L Provide your answer in degrees, rounded to one place after the decimal. d
