Final answer:
Modern cameras use electronic detectors called CCDs to absorb and record reflected light from objects.
Step-by-step explanation:
In modern cameras, reflected light from objects is absorbed and recorded using electronic detectors called charge-coupled devices (CCDs). When photons of light hit the CCD, they generate charged particles (electrons) that are stored and counted at the end of the exposure. The areas where the radiation is counted are known as pixels, and modern detectors can count the photons in millions of pixels.
