Light can be blocked electronically using materials that change their transparency or opacity in response to an electric field. One common method is using liquid crystal displays (LCDs) in which the alignment of liquid crystal molecules is controlled by applying an electric field to block or allow the passage of light. Another technique is electrochromic materials that change color and opacity when voltage is applied.

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 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 is observed when white light strikes a block of charcoal?
When white light strikes a block of charcoal, the charcoal absorbs most of the light across the visible spectrum, reflecting very little back. This results in the block appearing black in color due to the absorption of all colors of light.
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.
What will happen when a ray of light is shone at a glass block?
When a ray of light is shone at a glass block, it will refract (bend) as it enters the glass due to the change in the speed of light in the material. The light will then travel through the glass block, possibly reflecting off the surfaces inside, and refract again as it exits the block.

Who determines what swimmer touches wall first in Olympics?
on the wall their is a touch pad and when touched it goes off it is all recorded electronically, when near the end watch the side of the starting block a light will flash red.
How do I cancel a stolen phone?
Contact your phone company. They can 'electronically' block the phone from being used by the thief.

When was Block Island Southeast Light created?
Block Island Southeast Light was created in 1874.
How does a camera use light?
Electronically. To see what I mean, read the article link. Hope this helps.

Do curtains block the light out?
Curtains can help block out some light depending on their thickness and material. Dark, heavy curtains will be more effective at blocking light compared to sheer or light-colored curtains. Adding a blackout liner to curtains can also greatly increase their ability to block out light.
What happens when light hits a blue block?
Depends on the colour of the light, but with general white light, which is made up of many colours, the blue block absorbs all colours in the white light, apart from blue, which is reflected off the block into our eye, which is why the blue block appears blue to our eyes.

Does glass block infrared light?
Yes, glass can block some infrared light, depending on the type of glass and its thickness.
