Day€“night rearview mirrors are common in cars. At night, when you tilt the mirror backward, the intensity and glare of headlights behind you are reduced (Fig. 23.22). The mirror is wedge shaped and is silvered on the back. The unsilvered front surface reflects about 5% of incident light; the silvered back surface reflects about of the incident light. Explain how the day€“ night mirror works.
