What is the visible light spectrum?

Back

The visible light spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from infrared rays to ultraviolet rays.

What type of waves does a campfire emit?

Back

A campfire emits infrared waves, which are felt as heat.

Front

What are X-rays used for?

Back

X-rays are used in medical imaging to take pictures of bones and internal structures of the body.

Front

What are microwaves commonly used for?

Back

Microwaves are commonly used in communication devices, such as cell phones, and in microwave ovens for cooking.

Front

What is the order of the electromagnetic spectrum from lowest to highest frequency?

Back

The order is: radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is infrared radiation?

Back

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves, primarily associated with heat.

Front

What are ultraviolet rays?

Back

Ultraviolet rays are electromagnetic waves with shorter wavelengths than visible light, known for their ability to cause skin tanning and sunburn.
