TWO TYPES OF WAVES

  1. Transverse
  2. 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.

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

  • Constructive Interference- red dots
  • Destructive Interference- blue dots

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.

SIMILARITIES AND DIFFERENCES IN DUAL PIN AND DOUBLE SPLIT INTERFERENCES

SIMILARITIES

  1. They both have constructive and destructive interference
  2. They both form two waves
  3. The two waves have similar interference pattern

DIFFERENCES

  1. Dual pin begins with two waveforms while double slit bends or diffracts a plane wave to two waves
  2. Double slit requires a barrier with gaps in order to form interference, double pin doesn’t.

WAVE REFLECTION

WAVE REFLECTION DIAGRAM

Big image

OUR WAVE REFLECTION #1 AT 45 DEGREES

  • Angle of Incidence is 45 degrees
  • Angle of Reflection is 45 degrees
Big image

OUR WAVE REFLECTION #2

  • Angle of Incidence is 30 degrees
  • Angle of Incidence is 60 degrees
Big image

OUR WAVE REFLECTION #3

  • Angle of Incidence is 40 degrees
  • Angle of Incidence is 50 degrees
Big image

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

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.
