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.

come closer and become far apart and become steam/gas

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
