How does frequency affect the speed of waves

The formula to find the speed of a wave 

speed = wavelength x frequency

speed and frequency are directly proportional so as one increases then the other one will increase as well. in this case  as the frequency increases then the speed of the wave will also increase.

hope this helps :)

An increase in wave frequency cause a decrease in wavelength while the wave speed remains constant.

Hoping this is what you are looking for.

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.
