Does the speed of light in air depends on wavelength and light frequency?

The speed of light in air does not depend on wavelength and light frequency. The speed of liht is a universal constant and is approximated to be 299,792,458 meters per second. 

The wavelength does affect the speed of light. The wavelength travels slower in the air because particles are scattered all over. Refraction also plays an important role in the speed of light.   Refraction is the act of bending of particles as they enter into a medium.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
