Yes. Specialized instruments called photodetectors are able to sense light.
Sensors are used to detect things, such as motion, light, or color.
security lights use resistors as the light out side falls the security light turns on and as it gets lighterbout side the light dimms and turns off, in bmw's the resistors are used to detect when the lights should come on as light gets brighter the car lights turn off.
Robot sensors detect different things and send different amounts of electricity to the Robot's controller board to tell their findings. Then the controller board uses these different amounts of electricity to interact with its surroundings. Example: Lets say you have a robot that is made to follow light. Lets say your robot has 3 light sensors. One in the front of your robot one on the right and one on the left side. The sensors will detect how much light is on the front, right, and left sides and send this data to the controller board. Then the controller board uses this data to tell the robot with direction to go.
Passive simply means that the unit does not emit IR light, but does detect it. All warm things emit some degree of IR. a PIR motion detector senses the difference between a warm body and the cold background. Active IR emits IR light to illuminate an area to be "seen" with it's CCD that is sensitive to IR. Most new Sony camcorders use active IR for "night vision". IR alone, with no modifier, simply refers to the spectrum of light known as Infra Red, which is slightly above human's vision range.
Phototrophic organisms are found in the Kingdom Protista, specifically in the subgroups of algae and some protists. These organisms use light to produce energy through photosynthesis.
Members of the Plant kingdom obtain their energy from light. Some members of Monera and Protista do as well. Animals and Fungi and some Protists and Monerans obtain food by "eating" other organisms.
Euglena is a genus of single-celled organisms that are part of the protist kingdom. They are commonly found in freshwater environments and have characteristics of both plant and animal cells. Euglena are known for their ability to photosynthesize like plants in the presence of light, and they can also feed on organic matter like animals.
Photosynthesis occurs in the Plantae kingdom, specifically in plant cells. This process allows plants to convert light energy into chemical energy in the form of glucose, which is essential for their growth and survival.
The light that our eyes can detect is known as visible light.
Yes, some bugs can detect infrared light.
Green algae belong to Kingdom Protista. Green algae is a very diverse type of algae. Actually, green algae is sort of similar to plants. The green algae contain two forms of chlorophyll and capture light energy to produce sugar in similar with the plant. However, unlike the plants the green algae are aquatic. The species are named algae because they are aquatic and make their own food.
eyes
this depends on the situation. normally all one would need is a thermal sensor in order to detect light
Humans cannot detect infrared light because our eyes are only sensitive to a limited range of wavelengths, known as visible light. Infrared light has longer wavelengths than visible light, making it undetectable to our eyes. Specialized equipment, such as infrared cameras, is needed to detect and visualize infrared light.
