WHY SMARTPHONES DON'T HAVE SOLAR PANELS 🤔🤔

    Why smartphones don't have solar panels? 

As we know smartphones are so smart why can't they have to add a solar panel to recharge. 

In 2009 SAMSUNG released the world's first solar powered cell phone.It is known as the Samsung guru E1107 and featured a solar cell built into its black plate.When exposed to sunlight,the cell generated electricity which in turn recharged the phones battery. 
As if a solar panel is set to mobile phone it may cause a fire with the heat generated from the solar panel. 

Also the mobile manufacturers got a doubt where to install the solar panel.


You would got a doubt "what about solar powered calculators".


Solar powered calculators only take a tiny amount of power as compared to charge a mobile with solar panels.

There are many problems to set a solar panel to recharge your mobile phone. So mobile manufacturers didn't giving out those types of smartphones.

WHY CANT WE SEE WIND Air is defined as a mixture of nitrogen,oxygen,and minute amounts of other gases that surrounds the earth and forms it atmosphere. Air is transparent to our eyes because we have evovled retinas that are sensitive to the wavelengths of light that pass through it unobstructed-otherwise we wouldn't be able to see anything at all. Wind is just moving air, caused by pressure differences in the atmosphere.  Low-pressure air is slightly less dense than high-pressure air and so has a lower refractive index, which affects the path of light rays slightly : stars "twinkle" in the sky because of tiny distortions in the atmosphere, but you can't observe the effect with ground level objects, because they are much nearer & your brain processes signals from your eyes to present as stable an image as possible.  But you can see wind in indirect ways, from the movement of hair, trees & clouds. The funnel of a tornado is visible because the pressure drop in t...
