Quantum Photoelectric Effect: Principles and Energy Dynamics

(21) a) Describe l dl explcn Eisten photoelectric effect and link conservacn cn l dl d energy principle. Principle : energy is neither created nor destroyed only transformed. b) Suppose a metal bearing on lq electromagenita Radia?Ná producnd photoelectric effect. Why q with increasing intensity l dl l not increase incidnt Radia?Ná Ec d ls electrons emitids?. Because hf Reported = wext + Ecmax. The Ec max dl dpnd not intensidad.Esta explicn s refers to a single atom intensity yl ace lo q mas aya electrons sq x unit d second q no aya can release more energy dlqs + Eq(23) To illuminate a surface light d cn Metalix increasing frequency starts sounding fotoelectons cnd l Amariya frequency corresponds to chlorine. A) qs Explik same material can be expected cn cn s radiate red light. What if cn radiates blue light?. The red light has less energy q Akella frequency XLQ yellow ql XLQ NSRF would not occur photoelectric effect. The blue is yellow ql + frequency XLQ whether there would be photoelectric effect.
