Which are characteristics of electromagnetic waves? check all that apply. they travel only through matter. waves with a higher frequency have a shorter wavelength. waves with a higher frequency have a longer wavelength. they all move at the same speed. they can travel through space.

Which are characteristics of electromagnetic waves? Check all that apply.

.

Waves with a higher frequency have a shorter wavelength.

They all move at the same speed.

They can travel through space.

The correct answers apply:

B)

D)

E)

Explanation:

B) Given that all electromagnetic waves pass through space at the same speed, a wave with a shorter wavelength must have a higher frequency, and vice versa. This relationship is depicted in the equation below:

                               Speed = Wavelength × Frequency

D) & E) All electromagnetic waves travel through empty space at the same speed. The speed, which is called light speed, is around 300 million meters per second (3.0 x 108 m / s). There's nothing else known in the universe that moves at this speed.

Cheers!

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
