All equations (ur welcome)

Question 1

density mass and volume?

Answer 1

p=m/v

Question 2

pressure force area?

Answer 2

p=F/A

Question 3

Use relationship for pressure differrence

Answer 3

p = h x p x g

the second p is the density thing

Question 4

relation ship between pressure + kelvin temperature of a fixed mass of gas at constant volume

Answer 4

P1/T1 = P2/T2

Question 5

use the relationship between the pressure and the volume of a fixed mass of a gas at a constant temperature

Answer 5

p1V1 = p2V2

Question 6

speed frequency and wavelength

Answer 6

v = f x Y

the y is upside down u feel me

Question 7

frequency and time period

Answer 7

f = 1/T

Question 8

relationship between refractive index, angle i. and angle r.

Answer 8

n = sin i/ sin r

Question 9

relationship between critical angle and refractive index:

Answer 9

sin c = 1/n

rearranged it is c = sin -1( 1/n
