Answer:
Polarized glasses contains a special filter that block dangerous intensity of lights which are reflected by flat surfaces and they help in reducing glare and discomfort
Explanation:
Sunlight scatters in all the direction. But when this light strikes with the flat surfaces, then the light which is reflected by the flat surface tend to become polarized, means the reflected light will travel in all directions. This reflecting light creates a dangerous intense light that causes glare and reduces visibility.
Polarized glasses contains a special filter that block this type of dangerous intensity lights, help in reducing glare and discomfort.
Therefore, by the above discussion it can be say that the polarized sunglasses particularly effective in reducing glares.
Answer:
We know that loudness is directly proportional to amplitude and SI unit of amplitude is Decibel So unit of loudness is decibel
Machine C. Machine A has an efficiency of 250/1000 = 0.25 = 25%, Machine B's efficiency is 350/500 = 0.7 = 70% and Machine C has an efficiency of 150/200 = 0.75 = 75%.
