Khushi 4 years, 1 month ago

A change which occurs without a change in the composition and chemical nature of the substance is called a physical change. It means that there is a change only in the physical properties of the substance. Properties like colour, hardness, rigidity, fluidity, density, melting point and boiling point are known as physical properties. Melting of ice or boiling of water is a physical change because ice, water and water vapours are chemically the same substance that is H2O.㋡

Pata nhi

Adithya Dev A 4 years, 1 month ago

In spherical mirrors, a distant object concentrates or appeares to converge its light rays to the focus. But, the rule for image formation states that a ray of light PARALLEL to mirror is reflected to the focus. Therefore, light from distant source is said to be parallel. But, actually, these light rays need not be parallel.
