Answer:

Red light has a longer wavelength and lower frequency than blue light.

Explanation:

The photon energy carried by the red light is lower than blue light. The higher the frequency of the photon, the greater its energy and the greater its wavelength, the lower its energy. Thus, red light has a longer wavelength and lower frequency than blue light.

What best describes a sound wave? transverse and electromagnetic longitudinal and mechanical longitudinal and electromagnetic tr

GalinKa [24]

Sound needs medium to travel and it can not travel without medium

so sound wave is a travelling wave

now we also know that sound wave propagate in form of rarefaction and compression.

So all medium particles travel in the direction of wave only

so it is a longitudinal wave also

so correct answer will be

<em>mechanical longitudinal </em>

What are some examples of gravitational forces that keep an object in orbit? Pls give at least 2-3 example if you can.

Lelu [443]

Answer:

Without any external forces a moving object will continue to move in a straight line. The gravitational force between the two objects will provide the centripetal force to keep the objects moving around one another.

1. satellite in orbit around the earth (motion of earth is negligible)

2. moon in orbit around the earth (center of motion several thousand miles

from center of earth)

3. earth in orbit around sun (center of rotation close to center of sun)

4. binary stars (if masses of stars are equal center of rotation is in middle)
