Answer:
Angle Angle Similarity Postulate
Explanation:
Answer:
1) The medium b has higher optical density.
2) If the optical densities of both A and B are same.
Explanation:
- The refractive index of a material determines the number of times the velocity of light in that material is slower than the velocity of light in a vacuum.
- The higher refractive index means slower propagation of the light in that medium.
- The refractive index of the medium determines the optical density of the medium.
- If the material has a higher refractive index, then its optical density is high.
- If the material has a low refractive index, then its optical density is low.
- The light bends towards the normal while refracting through the medium from a lower optical density medium to the higher optical density medium.
- If both the mediums has the same optical density, the direction of propagation doesn't change.
The correct answer is "wavelength". In fact, the wavelength of a wave is defined as the distance between two consecutive corresponding points of the wave: for instance, the distance between two consecutive crests, or the distance between two consecutive throughs.
