Slope of graph = 'V/'f= 1.28/3.25 = 0.394 x 10-14 = h/e
Calculate 'h': (slope) x (e) = (0.394 x 10-14) x (1.6 x 10-19) = 6.30 x
10-34 Percentage error from Planck's constant: ((6.626 - 6.30) /
6.626) x 100 = 4.9%
Depending on the exact performance and efficiency of the Photo Electric
tube, errors ranging from 3% up to 10% or even higher can be expected
in calculating Planck' Constant. Nevertheless, the method and the theory
is clearly demonstrated.
Discussion:
1) Draw the relationship between the frequency of light and the backing voltage.
2) Find the experimental value of Planck's constant and the error ratio.
3) Explain how light can behave as both a particle and a wave.
In the circuit shown, the voltage between A and B is UAB=24 V and remains constant. The resistance R3=36 2. To ensure that when the switch S is closed or open, the voltages across C-B are 6 V and 8V, respectively, find the values of R₁ and R2.DO NOT USE AI OR CHATGPT
