NEET Physics Refraction MCQ Question
If a wave gets refracted into a denser medium, then which of the following is true?
wavelength speed and frequency decreases.
wavelength increases, speed decreases and frequency remains constant.
wavelength and speed decreases but frequency remains constant.
wavelength, speed and frequency increases.
Correct Answer
Detailed Explanation
When a wave enters a denser medium, its speed decreases while the frequency remains constant, leading to a decrease in wavelength.
