Light through water in Human Eye and Colourful World – Class 10 Science Experiment

Chapter Name: Human Eye and Colourful World

Activity Name: Light through water in Human Eye and Colourful World

Activity Description:

Required Items:

Metal tray, water, mirror, white light source, white cardboard sheet.

Step by Step Procedure:

1. Fill a metal tray with water.
2. Place a mirror in the water at an angle to the water surface.
3. Direct white light onto the mirror so that it passes through the water.
4. Position a white cardboard sheet above the water surface to observe the colors formed.
5. Note down the names of the colors observed.

Experiment Observations:

• Colors are observed on the white cardboard sheet due to the refraction of light passing through water and being separated into its constituent colors.

Precautions:

1. Handle water carefully to avoid spills.
2. Ensure the mirror is clean and positioned securely in the water.
3. Use caution while directing light to prevent any accidental exposure to intense light sources.

Lesson Learnt from Experiment:

This experiment demonstrates how light undergoes refraction when passing through water, leading to the formation of colors. It helps learners understand the concept of refraction and its role in producing the colorful world we see around us.
