What does it mean to reflect light?

Back

To reflect light means to bounce back light rays when they hit a surface. Shiny surfaces like mirrors and aluminum reflect light.

Front

What is absorption in terms of light?

Back

Absorption is the process by which an object takes in light energy and does not reflect it. Dark surfaces tend to absorb more light.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air into water.

Front

What happens when light hits a smooth surface?

Back

When light hits a smooth surface, it is reflected, allowing us to see clear images, like in a mirror.

Front

What is the role of a prism in light energy?

Back

A prism refracts light, separating it into different colors, creating a spectrum.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light, while refraction is the bending of light as it passes through different materials.

Front

What is a common example of light absorption?

Back

A common example of light absorption is a black shirt on a sunny day, which absorbs more heat than a white shirt.

Front

How does light travel?

Back

Light travels in straight lines until it hits an object or medium that can reflect, absorb, or refract it.

What is the importance of light in our daily lives?

Back

Light is essential for vision, photosynthesis in plants, and it provides warmth and energy.
