Questions and Answers

What is the process of heat transfer in an empty space or vacuum called?

Conduction
Convection
Absorption
Radiation (correct)

Explain the concept of refraction and give an example of where it occurs in everyday life.

Refraction is the bending of light as it travels from one material to another. An example of where it occurs in everyday life is when light passes through a glass of water, causing the image to appear distorted.

Which of the following is an example of heat transfer through radiation?

Melting ice in a glass
Feeling heat near a fire (correct)
Boiling water on a stove
Touching a hot pan

How does light behave like both a wave and particles? Provide an explanation and an example.

Light behaves like a wave because it exhibits properties such as diffraction, interference, and polarization. It also behaves like particles because it can be emitted and absorbed in discrete amounts called photons. An example of this is the photoelectric effect, where light can cause electrons to be emitted from a metal surface. Signup and view all the answers

Describe how a rainbow is formed and what causes its colors.

A rainbow is formed when sunlight passes through raindrops and is refracted, or bent, as it enters the droplet. The light is then reflected inside the droplet and refracted again as it exits, causing it to split into its component colors. This is known as dispersion. The colors of the rainbow are red, orange, yellow, green, blue, indigo, and violet, which can be remembered with the acronym ROYGBIV. Signup and view all the answers
