Do you know why ice cubes boil ( after they melt of course) faster than a water in a room temperature?

It is because solids absorb most heat.

Explanation:

The atoms within solids are tightly packed which makes transfer of heat within atoms easier with compared to the atom of liquids.

As soon as the solid melts it has enough kinetic energy to turn into gas faster.

c)as speed changes, wavelength and frequency change.

everything changes!

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
