Question

the higher a waves frequency is, the more energy it carries.
low - frequency radio waves can travel over long distances and can penetrate buildings, making them ideal for radio, television, and mobile phone communication. high - frequency waves like ultraviolet (uv) waves and x - rays carry more energy than radio waves. they are used in medical imaging and to sterilize surfaces and air. these high - energy waves can damage dna and other molecules in living tissue, so they are typically used in controlled settings.
a microwave carries more energy than a radio wave, but it is less suitable for communication because it cannot penetrate metal found in buildings. however, microwaves can be used to heat up food, unlike either radio waves or higher - energy uv waves.
select the true statements.
the frequency of an electromagnetic wave impacts its interactions with matter.
high - frequency uv waves may be used for mobile phone communication.
low - frequency radio waves do not damage human tissue.
x - rays carry more energy than microwaves.

Explanation:

• The text states that different - frequency electromagnetic waves (like radio waves, microwaves, UV waves, X - rays) have different properties such as energy levels and uses. For example, low - frequency radio waves are good for communication (can penetrate buildings), high - frequency UV and X - rays are used in medical imaging and sterilization (but can damage DNA). This shows that frequency impacts interactions with matter.
• Low - frequency radio waves are used for communication (radio, TV, mobile phones) and there is no indication that they damage human tissue in the context of their normal use (unlike high - energy UV and X - rays which are used in controlled settings).
• X - rays are a type of high - energy wave (mentioned as having more energy than radio waves, and microwaves have more energy than radio waves. Since X - rays are higher in the energy hierarchy than microwaves (as per the general electromagnetic wave energy order where X - rays are at a higher energy level than microwaves), X - rays carry more energy than microwaves.
• High - frequency UV waves are not suitable for mobile phone communication as low - frequency radio waves are used for that purpose.

Answer:

The true statements are:

• The frequency of an electromagnetic wave impacts its interactions with matter.
• Low - frequency radio waves do not damage human tissue.
• X - rays carry more energy than microwaves.
