1. The Kepler’s laws are: 

  • Kepler’s first law: The orbit of a planet is an ellipse with the Sun at one of the foci. 
  • Kepler’s second law: The line joining the planet and the Sun sweeps equal areas in equal intervals of time. 
  • Kepler’s third law: The square of orbital period of revolution of a planet around the Sun is directly proportional to the cube of the mean distance of the planet from the Sun. 

2. The orbits of the planet are elliptical in shape.

The wavelength of electron waves in two orbits `(lambda_(1) : lambda_(2))`

Correct Answer - A `lambda=(h)/(sqrt(2mKE)), (lambda_(1))/(lambda_(2))=sqrt((KE_(2))/(KE_(1))), (3)/(5)=sqrt((KE_(2))/(KE_(1))),(KE_(1))/(KE_(2))=(25)/(9)`
