What is light energy?

Back

Light energy is a form of energy that travels in waves and can be absorbed, reflected, or transmitted by materials.

How do solar panels work?

Back

Solar panels convert light energy from the sun into electrical energy through the photovoltaic effect.

Front

What happens when light is absorbed by a material?

Back

When light is absorbed by a material, its energy is transferred to the material, often causing a change in temperature or state.

Front

What is the difference between reflection and absorption of light?

Back

Reflection is when light bounces off a surface, while absorption is when light energy is taken in by a material.

Front

What type of light can increase electrical energy in solar panels?

Back

Visible light is the type of light that can increase electrical energy in solar panels.

Front

What is infrared light?

Back

Infrared light is a type of electromagnetic radiation that is not visible to the human eye but can be felt as heat.

Front

Why does sunlight affect thermal paper differently than flashlight light?

Back

Sunlight carries more energy than flashlight light, allowing thermal paper to change color when exposed to it.

Front

What is the role of energy in changing materials?

Back

Energy from light can cause materials to change by being absorbed, which may lead to heating or physical changes.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, infrared, and microwaves.

What is the significance of visible light for photosynthesis?

Back

Visible light is essential for photosynthesis as plants use it to convert carbon dioxide and water into glucose and oxygen.
