Question

Using a laser and soap water, study the
refraction of light under the guidance of your teacher.​

Answer 1

Refraction of light is the phenomenon by which a single monochromatic source of light emits a ray which is deviated by another medium when it passes through it. This is easily seen when we look through the side of a glass at a pencil on the other side.

To do an experiment to observe refraction, we use a laser and soap solution. We place the beaker containing soap solution on a stand with a white background behind it. We then shine the laser light directly at the soap solution, and observe it from the side against the white background.

We will be able to observe the refraction of light when we look at the given set up. However, precaution must be taken that one does not directly look into the laser as it will damage the eye and its sensory nerve cells.
