Question

directions: read the passage below and answer the following questions. a wave can be described as a disturbance that travels through a medium from one location to another location. picture a wave moving across the surface of an ocean, lake, pond or other body of water. when a pebble is thrown in a pond, it creates a disturbance and forms ripples which travel together as a front in a straight - line direction, or the waves may be circular waves that originate from the point where the disturbances occur in the pond. the wave is defined as the energy transferred through medium with regular vibration or oscillating motion. a few examples of waves are: water wave, light wave, electromagnetic wave, sound wave, seismic wave (earthquakes). the waves are classified mainly two types that are mechanical wave and electromagnetic waves. the sound waves are good example of mechanical waves which travel through mediums with the use of force. this force is exerted between molecules of the medium. electromagnetic waves do not need mediums to travel like light waves. these waves travel in straight lines in the perpendicular direction away from its source. 1. what is a wave? 2. name four examples of waves. 3. what are the two main types of waves?

Explanation:

1. A wave is a disturbance that travels through a medium with regular vibration or oscillating motion.
2. Water wave, light wave, sound wave, seismic wave.
3. Mechanical wave and electromagnetic wave.

Answer:

1. A wave is a disturbance that travels through a medium with regular vibration or oscillating motion.
2. Water wave, light wave, sound wave, seismic wave.
3. Mechanical wave and electromagnetic wave.
