Question

Difference between Reflection from denser medium and Reflection from rarer medium.​

Answer 1

Answer:

Explanation:

Denser medium

If the optical dencity of the median Is high then the speed of light in the median is low

Rearer medium

If the optical dencity of median is low then the speed of light in that median is high

Answer 2

Answer:

• Reflection from denser medium...

1. Wave velocity reverses
2. Particle velocity reverses
3. Crest will be reflected as trough and trough will be reflected as Crest
4. Phase change by 180°or π radian
5. Path change by lamda/2

• Reflection from rarer medium......

1. Wave velocity reverses
2. particle velocity does not reverses
3. Crest will be reflected as Crest and trough will be reflected as trough
4. No phase changes
5. No path changes
