What is the Color of a Mirror?

Image
By
The color of an object depends on which color it reflects. If an object reflects blue, it appears blue. If it reflects all colors, it appears white.

Now, a mirror reflects almost all colors. So that means, its color should be white, just like snow. But it's not!! Snow scatters light in all directions, making it appear white. But the mirror doesn't reflect light the same way. It reflects light at the same angle and direction from which it arrives. This is called specular reflection. Thus, it creates an image of whatever is in front of it. Now, mirrors best reflect light at wavelengths between 495 and 570 nanometers. The wavelengths in this range appear green to us. We can observe this when two mirrors face each other. In this case, the same image is reflected back and forth, making green color prominent

Why do the Indian telecom operators offer their services with 28 days validity, not 30 days?😡😡

By
Here telecom operator are very clever, b ecause telecom operators want to earn money of 13 months instead of 12 months. Let do the calculation and find out why telecom operators are offering 28 days validity. Each month they get 2 days more, therefore in a year they get additional 24 days. There are 7 month which has 31 days so they get additional 7 days.Now in case of February  ,it has only 28 days not 30. So the total number of days they get are=24+7-2=29 days. So if you recharge 12 times then more 29 days are left in a year.🤔🤔 Means for another 29 days you have to recharge from that telecom operator.😫😫 So you have to recharge 13 times in a year instead of 12 times in a year. So telecom operators provide 28 days validity only. First one telecom operator started and then another telecom operators also understood this concept and they also applied 28 days validity both in data packs and voice packs.😱😱😱

How Energy conversion from coal is done?

By
Single generator sets of over 600 MW are now used in the UK, though there are many smaller generators in use. A 600 MW generator can supplythe average needs of over 1 million UK households. Three or four such generators are typically installed in a single large coal-fired station which isoften sited close to a coal mine, away from the city dwellers who consume the electricity. Such generators are usually driven by a compound arrangement of highpressure, intermediate-pressure and low-pressure turbines, increasing in size as the pressure decreases. Modern turbines rotate in a speed range from 1500 to 3500 r.p.m., usually 3000 r.p.m. for the UK’s 50 Hz system. For large coal-fired plant the steam pressure could be 25 megapascals (MPa) with steam temperatures of 500–600 °C to improve the thermodynamic efficiency. In nuclear reactors, which operate under less demanding conditions, the steam is superheated to about 5 MPa and 300 °C. Modern water tube boilers are complex and have ...
