what is threshold frequency
Answers
Answer:
hii
your answer is here !
Explanation:
threshold frequency =]
Threshold frequency is defined as the minimum frequency of light which causes electrons to be emitted from a metal surface. If no electrons are ejected, this means that the frequency of the light is less than the threshold frequency.
follow me !
Answer:
Explanation:
Threshold frequency ;
Threshold frequency is the minimum frequency needed of an electro-magnetic wave in order for it allow the incident metal to emit electrons.
Example :
metal x may have a thresh hold frequency of y. if the electro-magnetic wave being shone upon it does not have a frequency higher than y, electrons will not be emitted. the higher the E.M wave’s frequency is than the the metal’s thresh hold, the higher the emitted electron’s kinetic energy
