Light ray 1 strikes the smooth surface, separating air and water as shown below. A horizontal line is drawn and the part above t
he line is labeled Air and the part below the line is labeled Water. There is one slanting ray labeled 1 which falls on the line at a point and there are four rays of light labeled 2, 3, 4, and 5 which move away from same point on the line. Ray 5 is exactly vertical to the line and below the line, ray 4 is on the right of ray 5 and makes an angle of about 25 degrees with ray 5. Ray 3 is above the line and makes an angle of about 25 degrees with the line. Ray 2 is on the right of ray 1 and ray 1 and ray 2 make angles of about 25 degrees with the vertical at the point where ray 1 strikes. Which of the following rays is the part of ray 1 that is reflected from the smooth surface? Ray 2 Ray 3 Ray 4 Ray 5
1-boyle's law (pressure and volume) 2- Charles' law (volume and temperature) 3- Avogadro's law ( number of mole and volume) 4- Gay-Lussac's law ( pressure and temperature)
