Question

Gurmit wanted to perform activity 16.8 using a laser torch. Her teacher advised her not to do so. Can you explain the basis of the teachers advise?


Solution

Intensity of the laser torch is very high as compared to the normal torch. Its light is concentrated in a very narrow beam and is highly energetic. It will damage the friend's eye if directly projected into it.
