Question
For principle quantum number n the number of different values of orbital quantum number 1 are n n - 1 n + 1 2n + 1 Young's double-slit experiment can be explained using phenomena of wave interference diffraction both a and b neither a not b Which of the following phenomena most clearly demonstrates the particle nature of light? diffraction. photoelectric effect interference refraction To avoid power losses electric power on transmission lines is transmitted at low voltages high currents high voltages low power According to relativity lengths of moving objects as opposed to not moving ones is measured to be shorter longer the same zero An electron in a hydrogen atom is in the n = 2 energy level. How many different quantum states are available to it? 2 6 8 18 In photoelectric effect the maximum energy of ejected electrons depends on frequency of the incident light, speed of the light, intensity of the light, amplitude of the EM wave Splitting a heavy nucleus into two followed by release of energy is called binding energy, nuclear fission nuclear fusion beta decay
Explanation / Answer
1) if principle quantum number is n
l will be from -(n-1) to n-1
so number will be 2n-1=>Answer
(2)it can be explained by both (a) and (b) so (c) is the option
(3)particle nature of light is shown by photoelectric effect
