In the experiment that was showing two photons hitting the detector when only 1 was fired through the slit, how did technology detect photons without mass to hit the detector ?

Cameras detect photons by utilizing a light-sensitive sensor, such as a CCD or CMOS chip. When photons enter the camera's lens, they hit the sensor and create an electrical charge, which is then translated into an image by the camera's processing software.
Yes, it is possible to detect individual photons using specialized equipment such as single-photon detectors. These detectors have high sensitivity and can detect even very low levels of light.
A spectrometer works by breaking down light into its component wavelengths using a diffraction grating or prism. Photons of different wavelengths will produce different patterns on the detector, allowing scientists to determine the composition of the light source.
In space, photons are detected using telescopes equipped with specialized detectors, such as charge-coupled devices (CCDs) or photomultiplier tubes (PMTs). These detectors are highly sensitive and can detect even very faint signals from distant sources.
The energy of individual photons can be measured using a device called a photon energy detector. This detector uses a material that produces a small electrical current when struck by a photon. The strength of the current is proportional to the energy of the photon, allowing scientists to measure its energy level.
