Explanation

• When you run a plastic comb through your dry and non-oily hair, the comb becomes statically charged.
• This static charge causes the comb to attract small, light objects like bits of paper.
• When you hold the comb above the paper, the paper is attracted to the comb due to the electrostatic force.

Explanation

• When the Moon and the Sun are on the same side of the Earth, we see a New Moon.
• This occurs when the Moon is between the Earth and the Sun, making the side of the Moon facing the Earth unilluminated.

Explanation

• When the Moon and the Sun are on opposite sides of the Earth, we see a Full Moon.
• This occurs when the entire face of the Moon is illuminated by the Sun, making it visible all night long.

Explanation

• The Moon is illuminated because it reflects the light from the Sun.
• The Moon's surface reflects the sunlight, making it visible to us on Earth.

Explanation

• When Earth is between the Moon and the Sun.
• It blocks the sunlight from reaching the Moon, casting a shadow on the Moon.
• This is known as a Lunar Eclipse.

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

Opaque objects form sharp and dark shadows because they block all light from passing through, creating a clear and defined shadow.

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.
