How far does a beam of light travel in 1 ns?

Short Answer

Expert verified
Answer: A beam of light travels approximately 0.2998 meters in 1 nanosecond.

Step by step solution

01

Convert time from nanoseconds to seconds

To convert 1 nanosecond to seconds, we can use the conversion factor 1 second = 1 x 10^9 nanoseconds. Therefore, 1 ns = 1/(10^9) seconds.
02

Apply the distance formula

Now we can use the distance formula with the speed of light (2.998 x 10^8 m/s) and the converted time value (1/(10^9) seconds). So, distance = (2.998 x 10^8 m/s) x (1/(10^9) s).
03

Calculate the distance

Multiplying the speed of light by the time value, we get distance = (2.998 x 10^8 m/s) x (1/(10^9) s) = 0.2998 m. Hence, a beam of light travels approximately 0.2998 meters in 1 nanosecond.

Polarized light of intensity \(I_{0}\) is incident on a pair of polarizing sheets. Let \(\theta_{1}\) and \(\theta_{2}\) be the angles between the direction of polarization of the incident light and the transmission axes of the first and second sheets, respectively. Show that the intensity of the transmitted light is $I=I_{0} \cos ^{2} \theta_{1} \cos ^{2}\left(\theta_{1}-\theta_{2}\right)$.
The radio telescope in Arecibo, Puerto Rico, has a diameter of $305 \mathrm{m}$. It can detect radio waves from space with intensities as small as \(10^{-26} \mathrm{W} / \mathrm{m}^{2} .\) (a) What is the average power incident on the telescope due to a wave at normal incidence with intensity \(1.0 \times 10^{-26} \mathrm{W} / \mathrm{m}^{2} ?\) (b) What is the average power incident on Earth's surface? (c) What are the rms electric and magnetic fields?

Two identical television signals are sent between two cities that are \(400.0 \mathrm{km}\) apart. One signal is sent through the air, and the other signal is sent through a fiber optic network. The signals are sent at the same time but the one traveling through air arrives \(7.7 \times 10^{-4}\) s before the one traveling through the glass fiber. What is the index of refraction of the glass fiber?
Light polarized in the \(x\) -direction shines through two polarizing sheets. The first sheet's transmission axis makes an angle \(\theta\) with the \(x\) -axis and the transmission axis of the second is parallel to the \(y\) -axis. (a) If the incident light has intensity \(I_{0},\) what is the intensity of the light transmitted through the second sheet? (b) At what angle \(\theta\) is the transmitted intensity maximum?

The currents in household wiring and power lines alternate at a frequency of \(60.0 \mathrm{Hz}\). (a) What is the wavelength of the EM waves emitted by the wiring? (b) Compare this wavelength with Earth's radius. (c) In what part of the EM spectrum are these waves?
