We conducted fun experiments examining the formation and propagation of sound and light, and the effects of energy.
Students studied the refraction of light using lenses. The change in direction of light as it passes from one transparent medium to another is called refraction of light.
The refraction of light is due to the density difference of the medium.
Sound is produced as a result of vibratory action. Sound propagates in all directions and in waves. Sound waves have energy.
Light rays emanating from a light source propagate linearly in all directions.
When light rays interact with a substance, the return of rays to the medium from which they came to a surface is called reflection of light.
