Frequency and Wavelength Relationships

Which of the following describes frequency?

• Number of times a complete cycle occurs

• distance between two points on a wave

• the magnitude of a signal- Ex loudness

• The crest of a wave

What is the relationship between frequency and wavelength?

• Inverse- if frequency increases the wavelength decreases.

• Inverse- if frequency decreases the wavelength decreases.

• direct- if frequency decreases the wavelength decreases.

• cyclic relationship-repeats itself over time

Which type of wave requires a medium

(material substance) to travel through?

• Lightwave

• both light and sound

• Sound wave

• x-ray

Which part of the electromagnetic

spectrum has the longest wavelength based on the provided chart?

• visible light

• x-rays

• gamma rays

• radio waves

When light travels from air into glass,

what happens to its speed? (This is why you don't get a sunburn while studying next to a window!)

• it stays the same

• it increases

• it decreases

• it becomes zero

Mrs. Durham has a guitar. When she increases the tightness on the string using the tuning peg, the frequency of the wave also increases. Does this cause the sound to pitch up or pitch down?

• The sound pitches up

• The sound pitches down

• The sound doesn't change

• None of the above

Which of the following best describes the sound being absorbed by the material.

• two or more waves overlap and combine to produce a new wave

  pattern

• bending of waves around obstacles or the spreading of waves as

  they pass through narrow openings.

• A wave that can travel through the vacuum of space - does not

  require a medium

• energy of a wave is taken in and converted into other forms of

  energy.
