PhysicsQ&A Libraryst A student investigated the photoelectric effect and found that the threshold frequency for a the particular metal was 6.0x1014 Hz. When light with a frequency of 9.0 x 1 0 Hz was shone onto the The student was surprised to find le same metal surface the stopping voltage was recorded as 0.42 that doubling the frequency of the incident radiation did not double the stopping voltage, nor did it double the current flowing. le Account for the student's observations. 1 Srec 9 M VeQuestion
