The laws of refraction and reflection are the same for sound and for light.? The speed of sound is 340 m/s in air and 1510 m/s in water. If a sound wave that is traveling in air approaches a flat water surface with an angle of incidence of 11.7◦ , what is the angle of refraction? Answer in units of ◦ .

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

+15-35=-20

going in opposite directions

snell's law

refractve index = sin incidence / sin refraction

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
