When light falls on an object which side do shadows fall?
The shadow will fall on the opposite side that the light hit the object. Assuming that the object is a solid object that you cannot see through, there would be no light on the other side, hence causing the shadow.
Is a shadow translucent?
The shadow is not a solid 'black' colour. It can be the same colour as the object and the shadow allows you to see through it more than an opaque objects shadow. An opaque object would block the light but a translucent object would give a shadow that you could quite easily see through
What are cathode rays made from?
Cathode rays are a stream of electrons originating from cathode and moving to an anode, when high voltage electric potential is applied to the electrodes sealed in a glass tube containing gas at low pressure.Cathode rays are stream of negativley charged electrons getting detached right from neutral molecues due to high voltage and driven right from cathode to anode.
What is it called when a meteor produces enough light to cast a shadow on the earth?
A meteor does not produce light, a shadow on the Earth is caused when the meteor blocks the Sun's rays. The meteor does this when it is placed in between the Sun and the Earth, this is called an eclipse.
How do the shadow stay the same throughout the day?
Shadows stay the same throughout the day because they are created by the position of the sun relative to the object casting the shadow. As the sun moves across the sky, the shadow's direction and length change, but the shape and size of the object casting the shadow remain constant. This creates the appearance of a consistent shadow.
Why cathode rays cast a shadow when an object is placed in their path?
Cathode rays are particles with mass and energy, which can be obstructed by solid objects in their path. When an object is placed in the path of cathode rays, the particles are blocked from passing through, creating a shadow on the opposite side of the object. This occurs because the object absorbs or scatters the cathode rays, preventing them from continuing in a straight line.
Can an opaque object produce a shadow?
Yes. Definitely it produces but its intensity will be low.answer 2 In general ONLY opaque objects will produce a shadow. A truly transparent object would not produce a shadow. Look up Opaque in your dictionary.
What is the object shadow?
An object shadow is a dark area created on a surface when light is blocked by an object placed in its path. The size and shape of the shadow depend on the angle and intensity of the light source, as well as the distance between the object and the surface.
What affects was the size of a shadow?
The size of a shadow depends on, the angle that the light source is hitting the object and the size of the object. In some cases, the amount of light can also affect the size of a shadow.
What causes a shadow to change shapes?
the object blocking the light or the light source are moved or changed. A shadow is created when an object is placed in the path of light. If the object remains unchanged then the movement of the light that is casting the shadow will alter the shape.
Why does blocking a light source with an object produce a shadow?
When light is blocked by an object, it cannot pass through that object, creating a shadow. The shadow appears on the surface behind the object because there is no light reaching that area. This occurs because light travels in straight lines and when an object obstructs its path, a shadow is formed.
Can an object have more than 1 shadow?
Yes, an object can have more than one shadow if there are multiple light sources casting different shadows from different angles. Each light source will produce its own distinct shadow.
Does a mirror form a shadow in the dark?
Shadows can only form when there is light present. A shadow is the result of a solid object blocking visible light. As a mirror is a solid object it can indeed produce a shadow, but nothing can form a shadow in the dark, there must first exist a light source.
Why does an object cast shadow on a screen 7 std science?
When a opaque object is placed between the source of light and the screen light from the source falls on a screen aceept some part which looks the shape of the object the Part of the screen wre high does not fall due to the object is called a shadow
How can you see shadow with the light on?
Shadows are created when an object blocks light from reaching a surface. Even with a light source present, an object placed between the light source and a surface will block some of the light and create a shadow on the surface behind it.
Why do the object's shadow is bigger than the object?
The object's shadow appears larger than the object because the sun's rays hit the object at an angle, causing the shadow to stretch away from the light source. This creates the illusion of the shadow being larger than the object itself.
Can a shadow be smaller than the object?
Yes, a shadow can be smaller than the object casting it. This can happen when the light source is very close to the object or when the object is very close to the surface on which the shadow is cast. The size of the shadow is determined by the angle of the light rays hitting the object and the distance between the object and the surface.
