Which of the following statements about light is true?(1 point)
Which of the following is the best option?
a) The speed of light in a vacuum depends on the wavelength of the light.
b) Light cannot travel through a vacuum.
c) The speed of light in a vacuum is 3⋅108 m/s.
d) The speed of light in a vacuum depends on the frequency of the light.
c) The speed of light in a vacuum is 3⋅108 m/s.
To determine which statement about light is true, we need to consider the information given in the options.
a) The speed of light in a vacuum depends on the wavelength of the light.
This statement is incorrect. The speed of light in a vacuum is constant and does not depend on the wavelength.
b) Light cannot travel through a vacuum.
This statement is incorrect. Light can travel through a vacuum because it doesn't require a medium to propagate.
c) The speed of light in a vacuum is 3⋅108 m/s.
This statement is correct. The speed of light in a vacuum is approximately 3⋅108 meters per second.
d) The speed of light in a vacuum depends on the frequency of the light.
This statement is incorrect. The speed of light in a vacuum is not dependent on the frequency of the light.
Therefore, the correct statement about light from the given options is:
- c) The speed of light in a vacuum is 3⋅108 m/s.
The correct statement about light is:
d) The speed of light in a vacuum depends on the frequency of the light.
