WAVE PRESENTATION

WHAT IS A WAVE

• A wave is disturbance of physical that travels through matter and space accompanied by a transfer of energy

WHAT ARE THE TWO TYPES OF WAVES

• Longitudinal
• Transverse
• Transverse

EXAMPLES OF TRANSVERSE AND LONGITUDINAL WAVES

• Transverse wave is a moving wave that consist os oscillation
• Longitudinal waves are waves in which the displacement of the medium is thesame or the opposite of the wave

WHAT IS REFLECTION

• Reflection is the change of an interference between two different media

WHAT IS RAREFACTION

• Rarefaction is the decrease in a object's density

WHAT IS DIFFRACTION

• Diffraction is the process by which beam of light or other system of waves is spread out as a result of passing through a narrow aperture

CONSTRUCTIVE AND DESTRUCTIVE INTERFERENCE

• Constructive interference is when two waves combine in the result of one bigger wave
• Destructive interference is when two waves combine in the result of a smaller wave

ONE INTERESTING THING LEARNT IN THIS CHAPTER

• Light waves do not need a medium to travel
