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.

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
