TWO TYPES OF WAVES
- Transverse
- Longitudinal
TRANSVERSE WAVES
WHAT IS A TRANSVERSE WAVE?
- Waves that are moving left and right, and also moving up and down.
WHAT CAUSES TRANSVERSE WAVES
- All waves are created by vibrations and/or disturbances.
TRANSVERSE WAVE DIAGRAM
TRANSVERSE WAVES WE CREATED
- Vibrations and disturbances cause waves.
EVERYDAY EXAMPLES OF TRANSVERSE WAVES
- Ocean waves, how they are moving left to right, but the disturbance in moving up and down.
EVERYDAY EXAMPLES OF TRANSVERSE WAVES
Roller Coaster going up and down.
LONGITUDINAL WAVES
WHAT IS A LONGITUDINAL WAVE?
- A wave that only moves left and right.
WHAT CAUSES LONGITUDINAL WAVES?
- All waves are created by vibrations and/or disturbances.
LONGITUDINAL WAVE DIAGRAM
EVERYDAY EXAMPLES OF LONGITUDINAL WAVES
- A slinky being pushed and pulled on one side.
EVERYDAY EXAMPLES OF LONGITUDINAL WAVES
- Traffic stopping and going.
SPHERICAL WAVE
WHAT IS A SPHERICAL WAVE?
- The wave motion of the spherical waves spreads outwards in all directions.

PLANE WAVE
WHAT IS A PLANE WAVE
- The plane wave the front is perpendicular to the direction of the motion of the wave.

DUAL PIN INTERFERENCE
WHAT IS A DUAL PIN INTERFERENCE?
The interference between two sets of concentric waves that share the same frequency
DUAL PIN INTERFERENCE DIAGRAM
- Constructive Interference- red dots
- Destructive Interference- blue dots
OUR DUAL PIN INTERFERENCE
DOUBLE SLIT INTERFERENCE
WHAT IS A DOUBLE SPLIT INTERFERENCE?
- When there’s a two opening, and there’s a plane wave going through, the two openings will cause the waves to bend or defract which results in an interference pattern.
DOUBLE SLIT INTERFERENCE DIAGRAM
OUR DOUBLE SLIT
SIMILARITIES AND DIFFERENCES IN DUAL PIN AND DOUBLE SPLIT INTERFERENCES
SIMILARITIES
- They both have constructive and destructive interference
- They both form two waves
- The two waves have similar interference pattern
DIFFERENCES
- Dual pin begins with two waveforms while double slit bends or diffracts a plane wave to two waves
- Double slit requires a barrier with gaps in order to form interference, double pin doesn’t.
WAVE REFLECTION
WAVE REFLECTION DIAGRAM
OUR WAVE REFLECTION #1 AT 45 DEGREES
- Angle of Incidence is 45 degrees
- Angle of Reflection is 45 degrees
OUR WAVE REFLECTION #2
- Angle of Incidence is 30 degrees
- Angle of Incidence is 60 degrees
OUR WAVE REFLECTION #3
- Angle of Incidence is 40 degrees
- Angle of Incidence is 50 degrees
LAW OF REFLECTION STATES...
- When a ray of light is reflected from a smooth surface, the angle of reflection is equal to the angle of incidence.
WAVE DIFFRACTION
WHAT IS WAVE DIFFRACTION
- Various occurrence which occur when a wave encounters an obstacle or a slit
INNITIAL DIFFRACTION SET UP DIAGRAM
OUR INITIAL DIFFRACTION SET UP
INNITIAL DIFFRACTION SET UP OBSERVATION
- As the plain wave passes through the barrier’s gap, the wave bends into spherical shape.
BARRIER GAP CHANGED DIAGRAM
OUR BARRIER GAP CHANGED
BARRIER GAP CHANGED OBSERVATION
- As the barrier gap widens, the less the wave bends. But the more the gap tightens, the more the wave diffracts into spherical wave.
