Exam-style question
Try this first
What is the effect of increasing the wavelength of light on the angle of refraction when entering a denser medium?.
- A.The angle of refraction decreases
- B.The angle of refraction increases
- C.The angle of refraction remains the same
- D.The angle of refraction becomes zero
Model answer
What a good answer should say
- The angle of refraction increases
Explanation
Why this works
As the wavelength of light increases, the angle of refraction also increases when entering a denser medium, as described by Snell's law, which relates the angle of incidence to the angle of refraction based on the wave speeds.
