Question

A blink of an eye lasts around 0.350 s. How fardoes light in a vacuunt travel in that time?

Answer 1

Given:

Time taken for the eye blink = 0.350 s

Let's find how far does light in a vacuum travel in that time.

To find the distance, apply the formula:

`x=c*t`

Where:

x is the distance

c is the speed of light = 3.0 x 10⁸ m/s

t is the time taken = 0.350 s

Thus. we have:

`\begin{gathered} x=3.0*10^8*0.350 \\ \\ x=105000000\approx1.05*10^8\text{ m} \end{gathered}`

Therefore, the distance light in a vacuum travels in that time is 1.05 x 10⁸ m.

• ANSWER:

1.05 x 10⁸ m
