You are watching: How long (in ns) does it take light to travel 1.0 m in vacuum

## a) exactly how long (in ns) go it take light to take trip 1.0 m in a vacuum? b) What street does light take trip in water, glass, cubic zirconi

a) exactly how long (in ns) does it take light to travel 1.0 m in a vacuum? b) What street does light take trip in water, glass, cubic zirconia throughout the time it travel in 1.0 m vacuum?

**Answer:**

a

b

i

ii

iii

**Explanation:**

Generally the time taken to travel 1 m in a vacuum is mathematically stood for as

Here c is the rate of light through value

So

The street light travel in water is mathematically represented as

Here n_w is the refractive index of water through value 1.333

So

The distance light travel in glass is mathematically represented as

Here n_g is the refractive index of glass v value 1.5

So

The distance light travel in cubic zirconia is mathematically represented as

Here n_c is the refractive index of cubic zirconia v value 2.15

So
