76. 1 st Law of thermodynamics: Heat added to a system (gas) is equal to the work done by the gas plus its change in internal energy Work is done by the gas when the volume increases. Work is done on the gas when the volume decreases.

78. Efficiency – The ratio of the work done to the input heat (energy) The maximum efficiency of a heat engine is given by the Carnot equation.

80. WAVES AND OPTICS

81. The wave equation:

83. Waves slow down in different mediums. The ratio of the speed in a vacuum to the speed in the medium is the index of refraction

85. Refraction: The bending of light when it travels from one medium to another. The angle of incidence is related to the angle of refraction by snells law

87. Total internal reflection occurs when light travels between two mediums where n 1 >n 2. If the angle of incidence is greater than the critical angle, total internal reflection occurs.

89. The lens and mirror equation gives the relationship between the image distance, object distance and focal length

91. Magnification:

93. Double slit interference: Evidence that light is a wave. θ is angle to the nth order bright spot and x m is the distance. L is the distance to the screen and d is the slit separation

94. The same equation work for single slit diffraction except they give the dark spots.

95. Thin film interference: The thickness of the film determines whether constructive or destructive interference occurs.
