The frequency of light from a laser is 4.878 x10^ 14 s-1 hertz
<h3>Steps</h3>
v= c/ lambda
c= 3.00 x10^8 m/s
nm into meters
615nm (1m/ 1x10^9 nm) = 6.15x 10^-7 m
use frequency formula
v = 3.00 x10^8 m/s // 6.15 x10 ^-7
v = 4.878 x10^ 14 s-1 hertz
The frequency of light from a laser is 4.878 x10^ 14 s-1 hertz
<h3>What do you mean by frequency?</h3>
- The quantity of waves that pass a set location in a predetermined period of time is known as frequency.
- Therefore, if a wave passes through in half a second, the frequency is 2 per second.
- The frequency is 100 times per hour if it takes 1/100 of an hour.

Answer:Fossil Fuels Still Supply 84 Percent Of World Energy — And Other Eye Openers From BP's Annual Review.
20.9m = 1s
286.33m = 13.7s
To answer this you would multiply both sides by the amount of seconds she ran. The answer however is that she ran as far as 286.33m.
