Question

In order to provide the illusion of movement, at what speed (frames per second) is a sound film usually projected?

a. 16 fps
b. 24 fps
c. 20 fps
d. 18 fps

Answer 1

Sound films are typically projected at 24 frames per second to achieve smooth motion. This standard frame rate avoids flicker and creates the illusion of fluid movement for the audience.Correct option is b.

Step-by-step explanation:

In order to provide the illusion of movement, a sound film is usually projected at a speed of 24 frames per second (fps).

This standard has been established to ensure that the motion between frames is perceived as smooth and natural to the human eye, avoiding flicker that can occur at lower frame rates. Therefore,

the correct option from the choices provided is b. 24 fps. It's important to note that different frame rates can be used for different effects or technical requirements, but 24 fps is the traditional speed for cinema projection.
