Which type of wave needs a medium to travel?
sound waves, because they travel by oscillating electromagnetic fields
light waves, because they travel by oscillating molecules
light waves, because they travel by oscillating electromagnetic fields
***sound waves, because they travel by oscillating molecules***
What do both sound and light waves transfer?
***energy***
electricity
air
matter
How does an increase in amplitude affect sound and light waves?
***louder sound and brighter light***
higher-pitched sound and longer wavelengths for light
higher-pitched sound and brighter light
louder sound and longer wavelengths for light
What happens to the wavelength when the frequency increases?
The wavelength increases
***The wavelength decreases***
The wavelength increases if the speed increases
The wavelength stays the same
Which of the following is true about sound waves?
Sound would move faster in a pool of water than in a pool of Jello
Sound would move faster in a pool of rubber than in a pool of diamonds
***Sound moves faster in the ocean than in the air***
Sound moves faster in a lake than in the ocean
5/5, I promise! If not, then I am extremely sorry!

yes, all of Hewwo's answers are correct.
yuh
Hewwo is right
Dang man I got 4/5
All of them are right
5/5
Yo mama is wrong
5/5
Yo mama is wrong
3 was higher pitched sound and brighter
Nobody wanna talk about the fact that sound travels faster in the water than in air....that makes zero sense...at all 🤨
HEWWO is correct
got 4/5 hewwo is wrong
nvm hes right sorry
