Answer:
a) s
b) 3.41 mm
Explanation:
a)
We take the speed of light, c = m/s and the refractive index of glass as 1.517.
Speed = distance/time
Time = distance/speed
Refractive index, n = speed of light in vacuum / speed of light in medium
b)
We take the refractive index of water as 1.333.
Speed in water = speed in vacuum / refractive index of water
Distance = speed * time
d = 3.41 mm
A control variable is the one element that is not changed throughout an experiment.A dependent variable is a variable whose variation does not depend on that of another.A independent variable is a variable whose value depends on that of another.
