The minimum speed of the particle is the Speed of light in glass is c/μ=2×108m/s.
<h3>Why is the refractive index important?</h3>
The higher the refractive index the slower the light travels, which causes a correspondingly increased change in the direction of the light within the material. What this means for lenses is that a higher refractive index material can bend the light more and allow the profile of the lens to be lower.
Refractive index values are usually determined at standard temperature. A higher temperature means the liquid becomes less dense and less viscous, causing light to travel faster in the medium.

The answer is A. The outer lines change as it moves
A stretched rubber band is storing <em>elastic potential energy. (A)</em>
the unit for volt is v
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
Answer:
Average speed = 0.35 m/s
Explanation:
Given the following data;
Distance = 1.3 Km
Time = 62 minutes
To find the average speed in m/s;
First of all, we would convert the quantities to their standard unit (S.I) of measurement;
Conversion:
1.3 kilometres to meters = 1.3 * 1000 = 1300 meters
For time;
1 minute = 60 seconds
62 minutes = X
Cross-multiplying, we have;
X = 62 * 60
X = 3720 seconds
Now, we can calculate the average speed in m/s using the formula;
Average speed = 0.35 m/s
