Question

Label each of the following statements as true or false. For those that are false, correct the statement. (a) Visible light is a form of electromagnetic radiation. (b) The frequency of radiation increases as the wavelength increases. (c) Ultraviolet light has longer wavelengths than visible light. (d) X-rays travel faster than microwaves. (e) Electromagnetic radiation and sound waves travel at the same speed.

Short answer

a) True. Visible light is a form of electromagnetic radiation. b) False. The frequency of radiation decreases as the wavelength increases. c) False. Ultraviolet light has shorter wavelengths than visible light. d) False. X-rays travel at the same speed as microwaves. e) False. Electromagnetic radiation and sound waves do not travel at the same speed.

Step-by-step solution

Identify the statement as true or false

This statement is true. #b) The frequency of radiation increases as the wavelength increases.#

Identify the statement as true or false and correct the statement if it's false

This statement is false. The frequency of radiation decreases as the wavelength increases because they are inversely proportional to each other. The correct statement should be: "The frequency of radiation decreases as the wavelength increases." #c) Ultraviolet light has longer wavelengths than visible light.#

Identify the statement as true or false and correct the statement, if it's false

This statement is false. Ultraviolet light has shorter wavelengths than visible light. The correct statement should be: "Ultraviolet light has shorter wavelengths than visible light." #d) X-rays travel faster than microwaves.#

Identify the statement as true or false and correct the statement, if it's false

This statement is false. All forms of electromagnetic radiation, including X-rays and microwaves, travel at the same speed in a vacuum (the speed of light, approximately 299,792,458 meters per second). The correct statement should be: "X-rays travel at the same speed as microwaves." #e) Electromagnetic radiation and sound waves travel at the same speed.#

Identify the statement as true or false and correct the statement, if it's false

This statement is false. The speed of electromagnetic radiation is the speed of light (approximately 299,792,458 meters per second in a vacuum). The speed of sound waves is much slower, approximately 343 meters per second in the air at room temperature. The correct statement should be: "Electromagnetic radiation and sound waves do not travel at the same speed."
