Light ray travels from an rarer medium to an denser medium. Which of the following is incorrect if \( (0^{\circ} < i < 90^{\circ}) \).
- A Speed of the light decreases
- B Wavelength of the light decreases
- C Frequency of the light increases
- D angle of incidence > angle of refraction
Answer & Solution
Correct Answer
(C) Frequency of the light increases
Step-by-step Solution
Detailed explanation
When light enters a denser medium, its speed and wavelength decrease, causing the ray to bend toward the normal \((i>r)\). However, frequency is a fundamental property of the source and remains constant regardless of the medium the light travels through. C) Frequency of the…
