Unformatted text preview: Theory Question 2 Page 1 of 5 Theory Question 2: Watching a Rod in Motion Enter all your answers into the Answer Script . pinhole camera D rod x v Physical situation A pinhole camera, with the pinhole at = x and at distance from the D x axis, takes pictures of a rod, by opening the pinhole for a very short time. There are equidistant marks along the x axis by which the apparent length of the rod, as it is seen on the picture, can be determined from the pictures taken by the pinhole camera. On a picture of the rod at rest , its length is . However, the rod is not at rest, but is moving with constant velocity L υ along the x axis. Basic relations A picture taken by the pinhole camera shows a tiny segment of the rod at position . x ~ 2.1 (0.6) What is the actual position x of this segment at the time when the picture is taken? State your answer in terms of x ~ , , , D L υ , and the speed of light =3.00×10 c 8 m s-1 . Employ the quantities c υ β = and 2 1 1 β γ − = if they help to simplify your result. if they help to simplify your result....
