The observation that light travels in a straight line can be explained by the property of light known as rectilinear propagation. This property states that light travels in a straight line in a homogenous medium.

Refraction of light can best explain the apparent bending of a pencil when it is dipped in a glass of water. This is due to the change in speed of light as it passes from air into water, causing the light rays to bend.
Refraction can best explain the apparent bending of a pencil when it is dipped into a glass of water. Refraction is the bending of light waves as they pass from one medium to another with a different density, such as air to water, causing objects to appear shifted or bent.
The best light microscopes can magnify images up to 1500 times under optimal conditions using oil immersion lenses. This allows for detailed observation of cellular structures and processes.
One of the best observations of refracting light is the splitting of white light into its component colors when passing through a prism. This phenomenon, known as dispersion, allows us to see the rainbow of colors that make up sunlight.
The blue color of the sky is best explained by the scattering of sunlight by gas molecules and small particles in the Earth's atmosphere. These particles scatter shorter wavelengths (blue and violet light) more effectively than longer wavelengths (red and yellow light), causing the blue color of the sky that we see during the day.
