Galileo attempted to measure the speed of light by measuring the time elapsed between his opening a lantern and his seeing the light return from his assistant's lantern. what distance, d, must separate galileo and his assistant in order for the human reaction time, δt = 0.2 s, to introduce no more than a 14 % error in the speed of light? answer in meters.

The distance is .

Explanation:

Given that,

Time

The velocity is no more than a 14 % error in the speed of light.

So,

Velocity

We need to calculate the distance

Using formula of speed

Where, v = speed

d = distance

t = time

Put the value into the formula

We know that,

The one side distance d' is

Hence, The distance is .
