Multiple choice general knowledge science & technology

Almost all professional cameras have a shutter that also controls the amount of light that can enter the camera and expose an image. This shutter opens and closes and is set by a ‘shutter speed’ dial that is expressed in fractions. Therefore which number is the fastest in time of a second?

  1. 1/125th

  2. 1/25th

  3. 1/250th

  4. 1/8th

C Correct answer
Explanation

Shutter speed is expressed as fractions of a second. A larger denominator means a shorter exposure time, making the shutter faster. 1/250th second exposes the sensor for less time than 1/125th, 1/25th, or 1/8th second, making it the fastest shutter speed among the options.
