Waves and Electromagnetic Radiation Study Guide

The distance a wave travels before repeating -

• wavelength

• crest

• amplitude

• frequency

The distance a wave travels in a certain amount of time -

• frequency

• amplitude

• wavelength

• speed

The number of waves that pass a given point in a certain amount of time -

• frequency

• crest

• amplitude

• energy

Half the vertical distance from the trough to the crest of a wave -

• amplitude

• trough

• crest

• node

In a standing wave, the areas of no amplitude are called

• node

• antinodes

• rarefactions

• compressions

In a standing wave, the areas of the greatest amplitude are called

• antinodes

• nodes

• compressions

• rarefactions

The highest point of the wave is called this -

• crest

• trough

• standing wave

• sitting wave

The lowest point of the wave is called this -

• trough

• crest

• sitting wave

• standing wave

As two different sized waves meet, constructive interference may occur. This will result in the waves combining to create a new crest _______________ than the original wave.

• greater

• less

• wider

Calculate the speed of a wave: there are two formulas

• Formula: speed = distance/time

• Formula: speed = frequency x wavelength

• Formula: speed = frequency/time

• Formula: Speed = wavelength x time
