Physics Questions

If a micrograph is false-colored, it means that the computer has created the colour for the object since we know that the electron microscopes sees only black and white colours.

Microscopes are of three types. They are :

1) Optical microscopes

2) Electron microscopes

3) Scanning tunneling microscopes

Scanning tunneling microscopes are the microscopes that are used to view metal surfaces.

The strength of an electromagnet can be increased by increasing the cross-sectional area, increasing the number of turns, increasing current supply, increasing the length of the coiled wire.

Analog synthesis uses a mixture of complex sounds that are shaped by filtering. It is based on representing data in terms of measurable physical quantities, in this case sound waves.

The side view mirror, in all the vehicles we use only convex mirror. This mirror makes the objects and small to show them in the mirror. That's why in all such mirrors, "Ojects in the mirror are closer than they appear."
