Calculate the frequency of an indigo light wave with the wavelength of 4.45 x 10^-7 m. The speed of light is 3.0 x 10^8. ^ meaning to the power

6.74 x 10¹⁴Hz

Explanation:

Given parameters:

Wavelength  = 4.45 x 10⁻⁷m

Speed of light  = 3 x 10⁸m/s

Unknown:

The frequency of the indigo light  = ?

Solution:

To solve this problem, we use the expression below;

       V  = f ∧

V is the sped of light

f is the frequency

 ∧ is the wavelength

 Now insert the parameters and solve;

        3 x 10⁸  =  f x 4.45 x 10⁻⁷

         f  = 6.74 x 10¹⁴Hz

answer: option c.

explanation:

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
