When a ray of light enters from a rarer medium to a denser medium, which of the following properties of light does NOT change?
A. Velocity
B. Wavelength
C. Frequency✓ Correct Answer
D. Intensity
💡 Solution & Explanation
The frequency of a light wave is determined entirely by the source producing it and remains constant when passing from one transparent medium to another, whereas its velocity and wavelength decrease as it enters a denser medium. This principle forms the foundational basis for understanding refraction and Snell's law in optics.
