Intensity of light is reduced to one fourth because the light beam spreads as it approaches into a spherical region of area 4pir^2,i.e., Iprop1//r^2. But laser beam dose not spread, hence its intensity remains constant. Laser beam is is unidirectional,
Intensity of waves is inversely proportional to source of distance from source (because I prop (1)/(r^(2))) when distance become double then intensity become (1^(th))/(4) value they do not spread hence here intensity remains same. Following geometri
A. It decreases. B. It remains the same. C. It increases. D. It becomes zero. 相关知识点: 试题来源: 解析 C。解析:随着光照强度增加到一定程度,光合作用速率也会增加,文章中有“As the intensity of light increases, the rate of photosynthesis also increases up to a certain point.”。 反馈...
Luminous Intensity: Luminous intensity is referred as light intensity. It is the amount of the light emitted by the light source per unit time per unit solid angle. It is one of the seven fundamental quantities. Answer and Explanation:
The harmful effects of light pollution increase with the intensity of light and the area affected by light pollution. The most common negative effect of light pollution is a disruption of the Circadian rhythms of animals and humans. These rhythms are the natural cycle of sleep and wakefulness. ...
Home to King Edward Point Research Station, South Georgia Island is another ideal location for researching atmospheric and astronomic activity — in this case, magnetic storms and their effects, one of which is the intensity of auroras [source: Turbitt]. ...
Diffused light is a soft light with neither the intensity nor the glare of direct light. It is scattered and comes from all directions. Thus, it seems to wrap around objects. It is softer and does not cast harsh shadows. What Causes Light Diffusion?
Sensors come in a wide variety, and each type has strengths and weaknesses. This section provides a detailed look atlaser sensorsthat detect based on received light intensity. What Is a Sensor? A Comprehensive Look at Sensors Learn all about the principles, structures, and features of eight se...
used to detect the intensity of light. It is also known as a photoresistor or photocell. It is a passive electronic component, which means that it doesn’t require any power source to operate. Instead, it works by changing its resistance based on the intensity of light that falls on it...
Light pollution refers to the addition of excess light to the atmosphere in such a manner and intensity that causes disturbances to normal functioning of our bodies and even ecosystems.Light pollution is also known as Photo pollution or luminous pollution. Thus, this is the explanation for those ...
