How many nanoseconds does it take light to travel 3.50 ft in vacuum?
1 answer:
Answer:3.56 nanosecond
In this case, you are asked the time and given the light distance(3.5ft)
To answer this question you would need to know the velocity of light. Speed of light is <span>299792458m/s. Then the calculation would be:
time= distance/speed
time= 3.5 ft / (</span>299792458m/s) x 0.3048 meter/ 1 ft= 3.56
second or 3.56 nanosecond

Answer:
Inverse proportion, greater
Explanation:
The relation between wavelength (λ) and frequency (ν) is given by
Where speed of light in vacuum.
We can see from this equation that wavelength and frequency are related inversely.
Now,
Where 'E' is energy of electromagnetic radiation and 'h' is Planck's constant.
We can see from this equation that greater frequency (ν) will give greater electromagnetic radiation (E). As they are directly proportional.
Hence,
When decreasing electromagnetic radiation there is a(n) Inverse proportion relationship between wavelength and frequency and the greater the frequency, the greater energy the electromagnetic radiation has
