According to Albert Einstein's theory of photoelectric effect, metals will only emit electrons when the incident light has a frequency that is above the minimum or threshold frequency.
So if the frequency of the incident light is less than the threshold frequency then electrons will not be emitted from that metal.
Answer:
Answer below.
Explanation:
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
Answer:
These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). Each of these four spheres can be further divided into sub-spheres.
