For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off
a mirror that is 51.0 km due east and have it detected by a light sensor that is 135 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. Determine the angle that the normal to the mirror should make with respect to due west.
the ray of light travels due east 51000 m , bounces back from reflecting mirrors . The reflected light gets focused on a point 135 m south . Let the angle between incident light and reflected light be θ.
tanθ = 135 / 51000
θ = .1516 degree
= .1516 x 60 minute
= 9.09 minute
angle between incident ray ( east - west ) and normal = 9.09 / 2
<h3>The topic of quantum entanglement is at the heart of the disparity between classical and quantum physics: entanglement is a primary feature of quantum mechanics lacking in classical mechanics. ... In the case of entangled particles, such a measurement will affect the entangled system as a whole</h3>
The initial velocity of Ms. Stafford is , while her acceleration is This is a uniform accelerated motion, so we can calculate the total distance travelled by Ms. Stafford in a time of using the law of motion for a uniform accelerated motion:
