Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Question

LIGO: The LIGO experiment announced the discovery of gravity waves in 2016. Gravitational waves obey a wave equation and travel at the speed of light.

The frequency of some of the gravitational waves detected by LIGO was 470 Hz. What was the wavelength of these gravitational waves?

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.

A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 × 108 m/s). 1. 4 light-seconds 2. 3 light-minutes 3. 2 light-days 4. 2 light-days, but this time answer in miles (enter just the number with no units)
