Heat Transfer and Electromagnetic Spectrum

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three main methods of heat transfer?

Back

The three main methods of heat transfer are conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.

Front

What type of radiation can cause sunburn?

Back

Ultraviolet (UV) radiation can cause sunburn and skin cancer.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light, specifically longer than red light.

Front

Which color of visible light has the shortest wavelength?

Back

Violet has the shortest wavelength in the visible light spectrum.

Front

What is the relationship between wavelength and energy in electromagnetic radiation?

Back

Shorter wavelengths correspond to higher energy, while longer wavelengths correspond to lower energy.
