Question

Explain an experiment to analyze scattering experiment in 10th physics solition

Answer 1

Answer:

The atom was believed to consist of a positive material "pudding" with negative "plums" distributed throughout. Rutherford directed beams of alpha particles (which are the nuclei of helium atoms and hence positively charged) at thin gold foil to test this model and noted how the alpha particles scattered from the foil.

Answer 2

Explanation:

All electromagnetic waves travel at the same speed through empty space. That speed, called the speed of light, is 300 million meters per second (3.0 × 108 m/s). ... For example, light travels more slowly through water than it does through air (see Figure below)
