If the dilated time t' and that the original time be t then we must have,
v is the velocity with which the clock moves
The clock loses 2.1 ns and 1 day in terms of second is
So, we must have,
Expanding binomially and neglecting higher order terms we have
This is the required velocity

How do I solve? A light ray in air hits a piece of quartz at a 39.0 deg angle. Inside the quartz, the light slows down to 2.06 1048 m/s. At what angle does the light travel in the quartz? (Hint: find n.) (Water n 1.33, Air n 1.00) (Unit- deg) 003-20і9Acelha Corporation. All Rights Reserved.
A light ray in air hits a piece of quartz, at a 39.0 deg angle. Inside the quartz, the light slows down to 2.06 x 10^8 m/s. At what angle does the light travel in quartz? (Hint - water n =1.33, air n = 1.00) (answer will be in degrees) • note : this question has been posted before on chegg and answer given was 1.456 but that shows to be not the right answer.
The speed of light is now defined to be 2.99792458 x 108 m/s. (a) Express the speed of light to three significant figures. m/s (b) Express the speed of light to five significant figures m/s (c) Express the speed of light to seven significant figures. m/s Need Help? Read ItTalk to a Tutor
3. (15 points) A light ray is traveling horizontally through air and hits the rectangular glass block shown to the right. The block has a triangular, air-filled cavity within it. You may take the index of refraction of air to be mair 1 and the index of refraction of glass to be nglass 1.5 40° く enters the glass block. Sketch this refracted ray on the diagram to the right. a. Calculate the angle of traction when the light ray...
A light ray is travelling at 1.33 x 108 m/s through a medium and hits the interface of a second medium. The critical angle for total internal reflection is 50 degrees for this case. If the mediums were switched, and light was traveling now from the second medium to the first medium (same two mediums, however), what would be the incident angle needed, in degrees, with the respect to the normal, if the refracted angle is 33 degrees?
A light ray is travelling at 2.21 x 108 m/s through a medium and hits the interface of a second medium. The critical angle for total internal reflection is 54 degrees for this case. If the mediums were switched, and light was traveling now from the second medium to the first medium (same two mediums, however), what would be the incident angle needed, in degrees, with the respect to the normal, if the refracted angle is 32 degrees?
A light ray is travelling at 1.65 x 108 m/s through a medium and hits the interface of a second medium. The critical angle for total internal reflection is 51 degrees for this case. If the mediums were switched, and light was traveling now from the second medium to the first medium (same two mediums, however), what would be the incident angle needed, in degrees, with the respect to the normal, if the refracted angle is 21 degrees?
Version 1 0.) Red light propagates through window glass at a speed of 2.0 x 10 m/s. This means that bli light must propagate through vacuum at a speed of: A) 1.5 x 10 m/s B) 2.0 x 10 m/s C) 2.5 x 10 m/s D) 3.0 x 10 m/s E) No way to know with the information given, but it must be <3.0 x 10 m/s A screen red, yellow, blue glass 7.)
