Science

• Wave the disturbance of water and the change of position in one point to another
• Wave pulse a single unrepeated disturbance
• Wave train periodic disturbance
• Transverse wave- perpendicular and made up of alternating crest and trough
• Longitudinal wave- parallel and is composed of rare function and compression
• Sound- created by vibrating objects capable of producing an sensation on our auditory system
• Intensity- how the energy was transmitted can be detect by decibel
• Light energy radiant energy that was see by our naked eyes
• Light is given off by a luminous body
• Source of lights

  1.Natural light

  2.Artificial light
• mechanical wave cannot transmit energy
• electromagnetic wave can transmit energy
• Rare function corresponds to through
• Compression correspond to crest
