WAVES

WHAT IS A WAVE

• A wave is a disturbance in a solid, liquid, or gas as energy is transmitted through a medium.
• It can also carry energy through matter or space.

TWO TYPES OF WAVES

• Transverse waves/ particles move perpendicular in the direction of the wave
• Longitudinal waves/ particals vibrate parallel to the direction of wave motion

EXAMPLES

REFLECTION REFRACTION DIFFRACTION

• Reflection/ a bouncing back of a wave on a surface
• Refraction/ the bending of a wavefront as it passes between two objects
• Diffraction/ a change in direction of a wave

VELOCITY OF WAVE

• The formula for measuring the velocity is wave=frequency x wavelength

CONSTRUCTIVE AND DESTRUCTIVE INTERFERENCE

• Constructive interference is a wave which is bigger than the original two waves
• Destructive interference is when the sum of the two waves is less than one wave or zero
