Question

Two flat mirrors held together atone edge make an angle, theta. A bee sits near the intersection of the mirrors along the line bisecting the angle and angle theta. A student at A looking into the mirrors sees five bees, the real one plus four images equally spaced around the vertical axis at C. What is the value of angle theta?

A student at A looking into the mirrors sees five bees, the real one plus four images equally spaced around the vertical axis at C. What is the value of angle theta?

Explanation / Answer

if there are odd no of images seen we have the formula as = 360*/no.of images =angle theta

therefore we get theta= 360*/5= 72 degree
