Waves in Different Media Quick Check
1.) Which measure does not change when a wave moves from one medium to another?
-frequency-
2.) Water waves approaching the shore will slow down. Which statement describes another change that occurs?
-The wavelength decreases-
3.) As a wave travels from one medium to another, its wavelength triples. Which statement describes the speed and frequency in the new medium?
-The speed will triple, and the frequency will stay the same-
4.) Sonar systems used in water send out sound waves that reflect off the environment and then are detected. As water gets denser, the speed of sound in water increases. What would happen to the wavelength of a sonar wave as it moves into water with a 5% higher speed of sound?
-The wavelength would increase by 5%-
5.) An earthquake sends seismic waves outward from the epicenter. The waves travel through different media in different directions. What will be true for all people who feel the earth shaking?
-The earth will rise and fall with the same frequency-
weakinsomniac is all correct
I agree.
THESE ARE ALL CORRECT THANK U SM WEAKINSOMNIAC
Correct
All of these are correct thank you
WeakInsomniac, you are a LIFESAVER
where's the weird names in this one????!!!!!
CUM_EATER,
love the name lmao
To answer these questions, we need to understand some basic principles about waves and how they behave when they move between different media.
1.) Which measure does not change when a wave moves from one medium to another?
- The frequency of a wave does not change when it moves from one medium to another. The frequency of a wave is determined by the source producing the wave and remains constant regardless of the medium it travels through.
2.) Water waves approaching the shore will slow down. Which statement describes another change that occurs?
- When water waves approach the shore and slow down, the wavelength of the waves decreases. This is because the waves are interacting with the shallow water near the shore, which causes the waves to become shorter.
3.) As a wave travels from one medium to another, its wavelength triples. Which statement describes the speed and frequency in the new medium?
- When the wavelength of a wave triples as it moves from one medium to another, the speed of the wave will also triple. This is because the speed of a wave is directly proportional to its wavelength. However, the frequency of the wave will remain the same. Frequency is determined by the source of the wave and does not change when the wave moves between different media.
4.) Sonar systems used in water send out sound waves that reflect off the environment and then are detected. As water gets denser, the speed of sound in water increases. What would happen to the wavelength of a sonar wave as it moves into water with a 5% higher speed of sound?
- When the speed of sound in water increases due to denser water, the wavelength of a sonar wave would increase by the same percentage. In this case, if the speed of sound increases by 5%, the wavelength of the sonar wave would also increase by 5%.
5.) An earthquake sends seismic waves outward from the epicenter. The waves travel through different media in different directions. What will be true for all people who feel the earth shaking?
- For all people who feel the earth shaking during an earthquake, the earth will rise and fall with the same frequency. This means that the people will experience the shaking with the same rhythm or pattern. The frequency of the seismic waves remains the same as they travel through different media and reach different locations.
