1.Which type of wave needs a medium to travel? sound waves, because they travel by oscillating molecules

2.What do both sound and light waves transfer? energy
3.How does an increase in amplitude affect sound and light waves? louder sound and brighter light
4.What happens to the wavelength when the frequency increases? the wavelength decreases
5.Which of the following is true about sound waves? sound moves faster in the ocean than in the air

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!
(Works for connexus)

Nobody wanna talk about the fact that sound travels faster in the water than in air....that makes zero sense...at all 🤨

yes, all of Hewwo's answers are correct.

(C) Sound waves, because they travel by oscillating molecules

(C) Energy
(A) Louder sound and brighter light
(D) The wavelength decreases
(B) sound moves faster in the ocean than in the air

100% just did the quick check in Connexus

yuh

Hewwo is right

nvm hes right sorry

All of them are right

5/5

Yo mama is wrong

HEWWO is correct

got 4/5 hewwo is wrong
