How are waves used in our daily lives

How are waves used in our daily lives?
Thanks!:)

u use electromagnetic waves of certain wavelengths to see. Another certain range allows u to feel heat. u utilize pressure difference arrising from sound waves to perceive sound. we use mexican wave to show our appreciation in a football match. we use .wav file format to listen to music. we surf the wave at malibu to show off our hot bods.

what else?

Microwaves, radio waves, sound frequencies (waves)...are those the kind of waves youre thinking of?
