Light can be blocked by pebbles in a beaker due to the phenomenon of light scattering and absorption. The pebbles may scatter the light in multiple directions or absorb some of the light, preventing it from passing through easily. This can result in reduced light transmission through the beaker.

What happens when you shine a light at a glass block?
When light is shined at a glass block, some of the light is transmitted through the block, some is reflected, and some is absorbed. The transmitted light changes its direction due to refraction as it passes through the glass block.
What happens when light is shone at a block?
When light shines on a block, the block can either absorb, reflect, or transmit the light. The material properties of the block determine which of these actions occur. If the light is absorbed, the block will convert the light energy into heat. If the light is reflected, it will bounce off the block's surface. If the light is transmitted, it will pass through the block.
What happens when ray of light is shone through a block?
When a ray of light is shone through a block, it may get refracted (bent) as it passes from one medium to another. The amount of bending depends on the difference in optical density between the block and the surrounding medium. If the block is transparent, the light may pass through without much deviation, but if the block is opaque, then the light may be absorbed or scattered within the block.
How do objects block the passage of light through them?
Objects block the passage of light through them by absorbing, reflecting, or refracting the light. When light interacts with an object, it can be absorbed by the material, bounced off its surface, or bent as it passes through, resulting in the blockage of the light's path.
How can two polarizing block all light passing through them?
When two polarizing blocks are aligned in the same orientation, they allow light to pass through. However, if the blocks are oriented perpendicular to each other, they block all light because the second block blocks the polarized light that passed through the first block. This is due to the orientation of the polarizing molecules within the blocks, which only allow light waves vibrating in a certain direction to pass through.

Do pebbles glow in the dark?
Pebbles do not naturally glow in the dark. However, some pebbles are coated with a phosphorescent material that absorbs light and glows in the dark after being exposed to light.

Can an opaque object block light?
Yes, an opaque object can block light because it does not allow light to pass through it. When light hits an opaque object, the material absorbs or reflects the light, preventing it from passing through to the other side.
Is a block of wood opaque?
Yes, a block of wood is considered opaque because it does not allow light to pass through it. Wood absorbs and scatters light, making it difficult for light to travel through the material.
If you place a paper clip below a beaker and pour water into the beaker why can't the paper clip be seen from the side of the beaker?
This is caused by the refraction of light as it moves through the water. When light passes through anything translucent or transparent, it bends. You have noticed the same thing when swimming.
What is it called when light hits an object and some light goes through and some dont what is it called when the light does not go through the block?
Transparent = light goes through the object (like glass). Translucent = some light goes through the block but there is sufficient diffusion to prevent perception of distinct images. Opaque = No light can get through the object.
Why light cannot pass through a block of wood?
Light cannot pass through a block of wood because wood is an opaque material. When light encounters wood, it either gets absorbed or reflected by the wood's molecules, preventing it from passing through.
What happens when light passes through a glass block?
When light passes through a glass block, it undergoes refraction, which is the bending of light as it enters the glass and again as it exits. The speed of light changes as it moves from air to glass, causing the light rays to change direction.
