If a photon has frequency = 2.00 x 1014s-1 and the speed of light = 3.00 x 108ms-1, then what is its wavelength?

The photon has a wavelength of

Explanation:

The speed of a wave can be defined as:

(1)

Where v is the speed, is the frequency and is the wavelength.

Equation 1 can be expressed in the following way for the case of an electromagnetic wave:

(2)              

Where c is the speed of light.    

Therefore, can be isolated from equation 2 to get the wavelength of the photon.

(3)

Hence, the photon has a wavelength of        

Summary:  

Photons are the particles that constitutes light.

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.
