Shadows

Why do shadows appear darker on some surfaces than others?

• Shadows appear darker on rough or dark surfaces because they absorb more light.

• Shadows are always the same color regardless of the surface.

• Shadows appear lighter on rough surfaces due to increased light reflection.

• Shadows are darker on smooth surfaces because they reflect more light.

What is the effect of distance on shadow length?

• The shadow length remains the same regardless of distance.

• The farther an object is from the surface where the shadow is cast, the longer the shadow will be.

• The closer an object is to the surface, the longer the shadow will be.

• The shadow length increases only during the day.

How can you tell the time of day by looking at shadows?

• By observing the color of the shadows

• By estimating the length and direction of shadows, as they change with the sun's position.

• By counting the number of shadows present

• By measuring the temperature of the shadows

What is a silhouette?

• A bright shape or outline of an object that appears against a darker background.

• A dark shape or outline of an object that appears against a lighter background, often seen when the light source is behind the object.

• A detailed drawing of an object with colors and textures.

• A three-dimensional representation of an object.

How does the position of the sun affect shadows during the day?

• Shadows are always the same length regardless of the sun's position.

• In the morning, shadows are long and point west; at noon, they are shorter and point north; in the evening, they are long again and point east.

• Shadows only change direction but not length throughout the day.

• Shadows are shortest in the morning and longest at noon.

What is the role of light in creating shadows?

• Light travels in straight lines, and when an object blocks the light, it creates a shadow on the surface behind it.

• Light bends around objects, creating a shadow that is larger than the object.

• Light reflects off surfaces, which prevents shadows from forming.

• Light diffuses in all directions, making shadows less defined.

What happens to shadows at noon?

• Shadows are at their longest.

• Shadows are at their shortest.

• Shadows disappear completely.

• Shadows move in a circular motion.

What is the relationship between the height of an object and its shadow?

• Taller objects cast shorter shadows when the light source is low in the sky.

• Taller objects cast longer shadows, especially when the light source is low in the sky.

• The height of an object has no effect on the length of its shadow.

• Shorter objects always cast longer shadows than taller objects.

What factors affect the size of a shadow?

• The color of the object

• The position of the light source, the distance of the object from the surface, and the shape of the object.

• The temperature of the environment

• The material of the object

How do shadows change throughout the day?

• Shadows remain the same length and direction all day.

• Shadows change in length and direction as the sun moves from east to west in the sky.

• Shadows only change direction but not length.

• Shadows disappear completely at noon.
