Answer:
75000 Hz
Explanation:
f = V / λ (f= frequency, v=velocity of wave, lambda= wavelength)
alternatively, f = c / λ (f= frequency, c= speed of light- 3.00x10^8 m/s, lambda= wavelength)
f= [3.00x10^8 m/s]/[4000 m]
=75000 Hz
Answer: Thomson
Explanation: Thomson proposed the plum pudding model of the atom.
Two parts are stage and coarse focus
The graphs can be described as
So in case of inverse relationship we will obtain a curve not straight line
