Light refraction is the bending of light as it passes through different mediums, such as air, water, or glass. This is due to the change in speed of light as it travels through different densities.
Refraction can cause objects to appear distorted or shifted when viewed through different mediums. For example, a straw in a glass of water may appear bent due to the refraction of light passing through the water.
Wavelength and frequency are inversely proportional to each other. This means that as the wavelength of light increases, the frequency decreases, and vice versa.
When light passes through water droplets in the air, it is refracted and dispersed into its different colors. This creates the rainbow effect that we see in the sky.
A prism is a solid object with flat surfaces that can refract light and separate it into its different colors. A lens, on the other hand, is a curved object that can refract and focus light to create images. Both use the principle of refraction, but in different ways.
