Answer:
The magnetic force on a free moving charge depends on the velocity of the charge and the magnetic field, direction of the force is given by the right hand rule. While gravitational depends on the mass and distance of the moving particle and electric forces depends on the magnitude of the charge and distance of separation.
Explanation:
The magnetic force on a free moving charge depends on the velocity of the charge and the magnetic field and direction of the force is given by the right hand rule. While gravitational depends on the mass and distance of the moving particle and electric forces depends on the magnitude of the charge and distance of separation.
The magnetic force is given by the charge times the vector product of velocity and magnetic field. While gravitational force is given by the square of the particle mass divided by the square its distance of separation. Also electric forces is given by the square of the charge magnitude divided by the square its distance separation.
Answer:
O C. Light energy
Explanation:
it conducts energy in it and is an energy itself.
Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
frequency of light will not change with change in medium but it will depend on the source only
so here frequency of light will remain same in both water and glass and it will be same as that in air
Part b)
As we know that the refractive index of water is given as
so the wavelength in the water medium is given as
Similarly the refractive index of glass is given as
so the wavelength in the glass medium is given as
Part c)
Speed of the wave in water is given as
Speed of the wave in glass is given as
