Q : This is because the camera which took the pictures and the projector which shows them run at the same speed. R: When a film camera is running at normal speed, it takes twenty-four pictures a second. S: When the film is run through the film- projector in the camera twenty-four pictures a second appear on the screen. The proper sequence should be :
