Sun light filtering through a tree leaves often makes circular patches on the groung because

Ravi observed a beam of sun light passing through a small hole on the roof, into the room. It is formed because,

When we look into the sun through narrowed eyelids, we see colour pattern in space because of

White light while passing through a glass prism breaks up into light of different colocurs because

An electric current I enters and leaves a uniform circular wire of radius a through diametrically opposite points. A charged paricle q moving along the axis of the circular wire passes through its centre at speed v. The magnetic force acting on the particle when it passes through the centre has a magnitude
