2. A. differentiate transverse from longitudinal waves, and surface waves B. draw the parts of wave C. develop a positive and patient mindset to sincerely participate in the discussion D. practice the values of cooperation and respect LEARNING OBJECTIVES:

3. WAVES 1

4. It is a disturbance in a medium that transfers energy from one place to another. What is a Wave?

5. It is any substance that allows energy to travel through waves. What is a Medium? Water is the medium of ocean waves. Air is the medium through which we hear sound waves. The electric and magnetic fields are the medium of light. .

6. CHARACTERISTICS OF WAVE 2

7. Crest = Highest point of the wave Trough = Lowest point of the wave Wavelength = Distance from one crest/trough to the next (m) Wave Height = Height from trough to crest (m) Amplitude = distance from the center of wave to the bottom of the trough (m) 5 CHARACTERISTICS OF WAVE

8. TYPES OF WAVE 3

9. Types of Wave -- is a wave in which particles of a medium move perpendicular to the direction of the wave. Transverse Wave Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced upwards and downwards.

10. Types of Wave -- is a wave in which particles of a medium move perpendicular to the direction of the wave. Transverse Wave

11. Types of Wave -- It is a wave in which particles of a medium move parallel to the direction of the wave. -- Energy will begin to be transported through the slinky from left to right. As the energy is transported from left to right, the individual coils of the medium will be displaced leftwards and rightwards. Longitudinal wave

12. Types of Wave -- It is a wave in which particles of a medium move parallel to the direction of the wave. Longitudinal wave

13. Types of Wave -- It is also called a circular wave , the particles of the medium move in a complete circle. It is a wave in which particles of the medium undergo a circular motion. Surface wave In a surface wave, it is only the particles at the surface of the medium that undergo the circular motion. The motion of particles tends to decrease as one proceeds further from the surface.

18. NOTE TAKING 6

19. SUMMARY Wave is a disturbance in a medium that transfers energy from one place to another. Medium is any substance that allows energy to travel through waves. Water is the medium of ocean waves. Air is the medium through which we hear sound waves. The electric and magnetic fields are the medium of light. People are the medium of a stadium wave. Crest - Highest point of the wave Trough - Lowest point of the wave

20. SUMMARY Wavelength - Distance from one crest/trough to the next. Wave Height - Height from trough to crest. Amplitude - distance from the center of wave to the bottom of the trough. Transverse wave is a wave in which particles of a medium move perpendicular to the direction of the wave. Longitudinal wave is a wave in which particles of a medium move parallel to the direction of the wave. Surface wave is also called a circular wave , the particles of the medium move in a complete circle. It is a wave in which particles of the medium undergo a circular motion.
