1.	How can you show the diverging and the converging of light by using laser lights?
Answer» Aim : To show diverging and converging of light by using laser lights. Material required : Concave mirror, convex mirror, laser lights-2, screen, V-stand, Agarbathi. Procedure: Place a concave mirror on a V-stand and place the V-stand on a table. Take two laser lights. Focus the light rays of laser lights parallel to the axis of the concave mirror. The light rays (beams) incident on the concave mirror are reflected back and converge at one point. Place the screen to catch that converging point of reflected light rays. Light a Agarbathi near the table. Observation : We can observe path of the incident and reflected rays clearly in the smoke of Agarbathi. Now place a convex mirror on the stand. Again pass the laser light rays parallel to the principal axis at the convex mirror. Observation : We can observe diverging light rays. We cannot catch any converging point on the screen.

Answer»

Aim :

To show diverging and converging of light by using laser lights.

Material required :

Concave mirror, convex mirror, laser lights-2, screen, V-stand, Agarbathi.

Procedure:

Place a concave mirror on a V-stand and place the V-stand on a table.
Take two laser lights.
Focus the light rays of laser lights parallel to the axis of the concave mirror.
The light rays (beams) incident on the concave mirror are reflected back and converge at one point.
Place the screen to catch that converging point of reflected light rays.
Light a Agarbathi near the table.

Observation :

We can observe path of the incident and reflected rays clearly in the smoke of Agarbathi.

Now place a convex mirror on the stand.
Again pass the laser light rays parallel to the principal axis at the convex mirror.

Observation :

We can observe diverging light rays. We cannot catch any converging point on the screen.
