When light travels from one medium to another, certain properties undergo changes, while others remain constant. The correct answer regarding which property does not change is the frequency of light.
Understanding Light Properties
- Velocity: The speed of light varies depending on the medium. For instance, light travels faster in air than in water or glass.
- Wavelength: The wavelength of light changes when it moves between different media. This is due to the change in velocity; as light slows down in a denser medium, its wavelength decreases.
- Frequency: The frequency of light is the number of oscillations per second and remains constant when light transitions from one medium to another. This constancy is crucial because it ensures that energy is conserved. The frequency can be calculated using the formula:
\[ \text{Frequency} = \frac{\text{Velocity}}{\text{Wavelength}} \]
If the velocity decreases and the frequency stays the same, the wavelength must also decrease to maintain this relationship.
- Refractive Index: This is a measure of how much the light slows down in a medium compared to a vacuum. It changes between different media, influencing the speed and wavelength of light.
Conclusion
In summary, when light travels from one medium to another:
- Velocity and Wavelength change.
- Frequency remains constant.
- Refractive Index varies with the type of medium.
Thus, the correct answer to the question regarding which property does not change when light travels from one medium to another is indeed option 'C', Frequency.
