What happens to the photons that reach the sensor in our Cameras?

Question

I know that a picture to appear, light has to reach the individual sensors of a camera.

But what happens when those photons reach the camera sensor? Do they stay there and accumulate? Or do they pass through everything?

Answer 1

So, light behaves interestingly like a particle and a wave, depending on the scenario and how you measure it. In this case the photon would be easier to understand like a wave, which transfers energy to the camera sensor, which the sensor reads as a specific wavelength, and then the wave’s energy turns into heat on the sensor.

Have you ever put your hand in front of a very bright light and felt the heat? The same thing is happening inside the camera with less intensity, the camera just measures the wavelength of light as it hits the sensor.
