Question

9 blue light bends more than red light when it passes through glass. thus, blue light has a greater: a angle of refraction b interference pattern c index of diffraction d wavelength

Explanation:

1. Analyze Option A: When light passes through a medium (like glass), the angle of refraction depends on the refractive index. Blue light bends more, meaning its angle of refraction (the angle between the refracted ray and the normal) is greater compared to red light.
2. Analyze Option B: Interference pattern depends on wavelength and path difference, not directly on how much light bends in a medium. So this is not related.
3. Analyze Option C: There is no "index of diffraction"; the correct term is "refractive index". So this option has a misnomer and is incorrect.
4. Analyze Option D: Blue light has a shorter wavelength than red light, so it does not have a greater wavelength.

So the correct answer is related to the angle of refraction as blue light bending more implies a greater angle of refraction.

Answer:

A. Angle of refraction
