Must be sure about your answer

Answer 1

The correct answer is option a. "cameras that use photographic film".

Step-by-step explanation:

It is considered that light has a dual nature because it act as a particle and as a wave. The fact that cameras use photographic film to work illustrates the dual nature of light. The photographic film captures the image formed by light's reflection, and it does so by using a sensitive element such as silver halide that changes the structure when it reacts to the light photons (particle). Additionally to reacting with the particle, the films have layers of emulsion that produces the color when it interacts with different wavelengths of the light (wave).

Answer 2

The answer is A. Cameras that use photographic film.
Light has both properties of a wave and a particle.Light can be treated like a wave, but its energy is distributed in discrete packets called photons. Light can appear in different wavelength -- the greater the wavelength, the lesser energy it emits. This explains the existence of color! A chemical change occurs in the photographic detectors that are coated on the film when the energy in the photon of light hits the film. This process is called photochemistry.
