Simply put, because it bumps into things as it travels though a solid.
what is the material through which light travels
It travels much faster through pine wood than through air.
Molecules making up the air are far apart compared to the molecules making up any solid medium. As solids provides very less inter and inter molecular space, light often travels slowly through solid medium. Refractive index of air is 1.
Because it is light not heavy and lands slowly

No. Light can't travel through solid brick, steel etc, but sound can.
Yes. The more dense the material the slower light travels. Light travels the slowest in diamond at about a third of its normal speed of 300 000 km /s in a vacuum.
what is the material through which light travels
Light slows down when it travels through matter.The only time light travels at is maximum speed, c, is in a vacuum.

Because it is light not heavy and lands slowly
light travels from sun to earth through vaccum, so its easily understood
Light travels as light energy. Light is a type of electromagnetic wave.
glass
light is refracted when it travels through air and then through glass
