Answer 1

Ans A) The properties of light:

• Reflection of light.
• Refraction of light.
• Diffraction of light.
• Interference of light.
• Polarization of light.
• Dispersion of light.
• Scattering of light.

Ans B) things required for a shadow to form:

• a source of light.
• an opaque object.
• a screen or surface behind the object.

Ans C) Shadows are made by blocking light. Light rays travel from a source in straight lines. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object.

Ans D) We can convert an opaque sheet of paper to a translucent sheet,by dipping the paper into oil.

Ans E) arranges three pieces of card, with holes in, in an uneven line. The light stops and cannot travel through all three cards. When we arranges the holes in a straight line, the light can travel through.
