Question

Answer

Answer is c

Answer

An opeque thing is a thing  that light can not pass through so when a source of light reflects the light bounces

Answer

The answer is c because the opaque object reflects the light

Answer

To see a Shadow we need a source of light and an object because when there is a source of light and an opaque object. the opaque object blocks the source of light which has an effect and reflects its shadow on a screen

Answer

Because without an opaque material and a source of light we cannot make a shadow.

Answer

A source of  light and  an opaque  object  is the answer

Answer

Answer is option c

Answer

What is opaque object?

Answer

Explanation of Answer:
A source of light and an opaque object:
- Shadows are formed when an object blocks the path of light.
- An opaque object does not allow light to pass through it, thus creating a shadow.
- A translucent object allows some light to pass through, resulting in a partial or lighter shadow.
- A transparent object allows light to pass through completely, so it does not create a shadow.
- Therefore, the correct answer is C: A source of light and an opaque object is needed to see a shadow.A shadow is formed only when a source of light is obstructed by an opaque object.

To see a shadow we need a source of light from which light comes and opaque object to cast a dark shadow in colour of blue black

Answer

Option A will be right

Answer

Introduction:
To see a shadow, we need a source of light and an opaque object. This is because shadows are formed when light is blocked by an object, and only opaque objects have the ability to completely block light. Let us delve deeper into the reasons behind this phenomenon.

Explanation:
- Source of Light: In order to see a shadow, we require a source of light. This could be natural light from the sun or artificial light from a bulb or flashlight. Light is essential as it illuminates objects and enables us to perceive their presence.

- Opaque Object: An opaque object is one that does not allow light to pass through it. When light falls on an opaque object, it is unable to transmit through the object and is instead absorbed or reflected. This prevents the light from reaching the surface behind the object, creating an area of darkness called a shadow.

- Translucent and Transparent Objects: Translucent objects allow some light to pass through them, but the light gets scattered in different directions, making the object appear hazy or blurry. As a result, shadows formed by translucent objects are not as distinct as those formed by opaque objects. Transparent objects, on the other hand, allow light to pass through them without scattering or absorbing it. Therefore, transparent objects do not cast shadows, as light simply passes through them uninterrupted.

- Formation of Shadows: When light rays encounter an opaque object, they are unable to pass through and are blocked. The area behind the object, away from the light source, becomes devoid of light, creating a shadow. The shadow takes on the shape and size of the object, as it is an absence of light caused by the obstruction of the object.

Conclusion:
To see a shadow, we need a source of light and an opaque object. Opaque objects have the ability to block light, preventing it from reaching the surface behind them and creating a shadow. Translucent objects allow some light to pass through, while transparent objects allow light to pass through without obstruction. Shadows formed by opaque objects are more distinct and well-defined compared to those formed by translucent objects. It is through the interplay of light and the obstruction of an opaque object that shadows are formed and observed.
