Explanation

• If an opaque object is moved further away from the light source, the shadow gets smaller.
• This is because the light source appears smaller from a distance, casting a smaller shadow.

Explanation

When light strikes an opaque object, the light is blocked, thus a Shadow is formed on the opposite side of the object.

Explanation

• When a ray of light strikes a brick wall, it is reflected by the wall.
• This is because brick walls are opaque.
• It means they do not allow light to pass through them.
• Instead, the light bounces back, or is reflected, by the wall.

Explanation

• Butter paper is a translucent material because it allows some light to pass through.
• But also scatters some of the light, making it semi-transparent and creating a diffuse effect.

Explanation

• Translucent objects allow some light to pass through them.
• But also scatter or absorb some of the light, resulting in faint or diffuse shadows.

Explanation

• Transparent objects do not form shadows because they allow all light to pass through them.
• So there is no blocking of light to create a shadow.

Explanation

• Opaque objects do not allow any light to travel through them, as they absorb or reflect all of the light.
• Examples: Metals, wood, stone, paper, books, table, wall, newspaper, brick wall, wooden objects, trees and thick clothing.

Explanation

• Air is essentially transparent.
• It allows all light to pass through it without scattering or absorbing any of the light.

Explanation

• Transparent objects allow light to travel through them without scattering or absorbing any of the light.
• Examples: Glass, water, air, plastic and wrap.

Explanation

• Jupiter is a non-luminous object.
• Unlike burning coal, glassware and fireworks, which either emit or reflect light in ways that are noticeable.
• Jupiter does not generate its own light but reflects the light of the Sun.
