Question

how do digital cameras produce images?

by exposing an electronic sensor to light

by exposing chemicals on film to light

by exposing semiconductors to light

by exposing magnetic tape to light

Explanation:

Digital cameras use an electronic sensor (like a CCD or CMOS sensor) to capture light. Exposing chemicals on film is for traditional film cameras. Exposing semiconductors is too vague and not the primary mechanism, and magnetic tape is for storage (e.g., old video cameras) not image capture. So the correct option is the one about exposing an electronic sensor to light.

Answer:

A. by exposing an electronic sensor to light
