What do you think would be the observation if the α-particle scattering experiment is carried out using a foil of a metal other than gold?
If the α-scattering experiment is carried out using a foil of a metal rather than gold, there would be no change in the observation. In the α-scattering experiment, a gold...

Enlist the conclusions drawn by Rutherford from his α-ray scattering experiment.
Rutherford concluded from the α-particle scattering experiment that– (i) Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected. (ii)...

What is the angle of incidence of a ray if the reflected ray is at an angle of 90° to the incident ray?
As per the laws of reflection The angle of incidence ∠i = angle of reflection ∠r Here as given ∠i + ∠r = 90° ∴ ∠i + ∠i = 90 ° or ∠i =...
