Question

A laser beam is incident on a mirror at an angle of 30?,as shown in (Figure 1) . It reflects off the mirror and strikes a wall 6.0 m away at point P.

By what distance does the laser spot on the wall move if the mirror is rotatedby 10?? Please show work.

Express your answer to two significant figures and include the appropriate units. A laser beam is incident on a mirror at an angle&n

Answer 1

Answer #1

firstly r=i=30deg

Now after rotating, r= 2 x 10 deg rotate

distance of P from normal = 3.464m

New distance P' from normal = 7.15m

distance reqd = 3.686m

Answer 2

A small plane mirror is mounted on a wall. A laser beam is incident on the mirror at a 45° angle, as shown in the figure. The reflected beam makes a spot on a wall 5.0 ? from, and parallel to, the wall with the mirror. When you push on the wall with the mirror, you deform the wall a little, shifting the angle of the mirror slightly and moving the spot on the other wall. If the spot moves...

Mirror Laser Discharge 1.0 mm beam Partial mirror Electrodes Power supply Review A helium-neon laser (λ = e33 nm) is built with a glass tube of inside diameter 1。0 mm. as shown in (Figure 1). One mirror is partially transmitting to allow the laser beam out. An electrical discharge in the tube causes it to glow like a neon light. From an optical perspective, the laser beam is a light wave that diffracts out through a 1.0-mm-diameter circular The angle...
