Are you frustrated with the button presses to enter your laptop BIOS/firmware? Some laptop models don't recognize the 'Enter BIOS' command through key-press (like F2, F8 and so on). Follow the below procedure to easily get into the BIOS using Windows 10 Settings.


Step 1. Open the windows settings by clicking the windows menu on desktop and then the gear symbol as shown in the picture below.

Step 2. Open Update & security

Step 3. Open Recovery in the left tab and click Restart now under the Advanced startup
 

Step 4. The system will now enter into a blue background interface. Select Troubleshoot from the options

Step 5. Now select Advanced options

Step 6. Click UEFI Firmware Settings

Step 7. Click to Restart into the BIOS options. You are done. Happy BIOS updation !!!!

Important Atmospheric Layers for Electromagnetic Waves

The ionosphere is a region of Earth's upper atmosphere, from about 60 km (37 mi) to 1,000 km (620 mi) altitude, and includes the thermosphere and parts of the mesosphere and exosphere. It is ionized by solar radiation, plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth. The various layers of the ionosphere are listed below:

D-Layer
Height        : 70 Km
Thickness   : 10 Km
Disappears at night
Aid: Very low frequency & LF Waves.

E-Layer
Height       : 100 Km
Thickness : 25 Km
Disappears at night – due to the recombination of ions.
Aid: Medium frequency

ES – Layer
Sporadic E-Layer

F1-Layer
Height : 180 Km
Thickness : 20 Km
Combines with F2-layer at night.

F2-Layer
Most important layer.
Height: 300 Km – 400 Km (will come down to 250 Km at night)
Combines with F1-layer at night
Persist at night.
Low density of air layer because there is no collision between electrons.
During sun spot the deflection decreases.
