What happens when a wave enters a different material and slows down?

Refraction

Explanation: When a light wave hits a glass of water the wave bends to make it look side ways

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
