Answer:
pls mark me as brainliest.
Explanation:
1) sound - vibration that travel through the air or another medium can be heard when they reach a person's or animals ear is known as sound.
2) tuning fork - A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs formed from a U-shaped bar of elastic metal. It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object.
3) prism - A prism is defined as a transparent, polished flat optical element on which light reflects.
4) surface tension - Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects to float on a water surface without becoming even partly submerged.
5) radiation - Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties.
