Viral meningitis: Meningitis caused by many viruses is usually contagious. However, certain viruses that are transmitted by mosquitoes are usually not spread person to person, so they are not contagious.
3] Heat transfers through the glass by conduction 4] Heat transfers from the glass to the outside air via convection. If the temperature differences are small and there are no winds or drafts, transfer of heat to/from air/glass will be by conduction.
The light wave is absorbed by the object, never released in the form of light. Since different atoms have different natural frequencies of vibration, they will absorb different frequencies of visible light. Comment on the speed of light before it enters the glass, in the glass, and when it exits the glass. It is at 3 x 10 to the 8 entering, but slows down while going through the glass. It goes back to the original speed once it exits the glass back into the air.
