What are the different types of electromagnetic waves?

• Red waves, blue waves, green waves, yellow waves

• Sound waves, ocean waves, earthquake waves, wind waves

• Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays

• Solid waves, liquid waves, gas waves, plasma waves

Give an example of a use for radio waves.

• Communication purposes such as AM/FM radio, television broadcasting, and cell phone signals

• Using a flashlight

• Sending smoke signals

• Sending messages through carrier pigeons

Explain how infrared waves are used in remote controls.

• They are used to cook food from a distance.

• They are used to play music on the remote device.

• They are used to transmit signals to the electronic device being controlled.

• They are used to create a visual display on the remote device.

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

• Directly proportional

• Depends on the medium

• No relationship

• Inversely proportional

How are microwaves used in everyday life?

• Sending text messages

• Watering plants

• Playing music

• Cooking and heating food

What are the potential dangers of ultraviolet waves?

• Enhanced vision and improved skin health

• Skin damage, eye damage, and increased risk of skin cancer

• Decreased risk of skin cancer

• Increased risk of hair loss

Describe the application of X-rays in the medical field.

• They are used for medical imaging to diagnose and monitor conditions.

• They are used for transportation in the medical field.

• They are used for communication in the medical field.

• They are used for cooking food in the medical field.

What is the main difference between gamma rays and other types of electromagnetic waves?

• Gamma rays have the lowest frequency and energy.

• Gamma rays travel at the same speed as sound waves.

• Gamma rays have the highest frequency and energy.

• Gamma rays are visible to the human eye.

List three examples of how visible light is used in technology.
