An isolated metal plate is given a negative charge. Electromagnetic radiation is incident on the plate. The plate loses its charge due to the photoelectric effect. (a)? Discuss how the rate of loss of charge from the plate depends on the frequency and intensity of the incident radiation. In your answer you should explain why: ??? the plate loses its charge ??? the photoelectric effect occurs only for frequencies greater than a particular value ??? the rate of loss of charge increases with intensity for radiation above that particular value of frequency. Thank you

An isolated metal plate is given a negative charge. Electromagnetic radiation is incident on the plate. The plate loses its charge due to the photoelectric effect. {a} Discuss how the rate of loss of charge from the plate depends on the frequency and intensity of the incident radiation. In your answer you should explain why: - the plate loses its charge - the photoelectn'c effect occurs only for frequencies greater than a particular value - the rate of loss of charge increases with intensity for radiation above that particular value of frequency
