Foldables Waves Make the following Foldable to compare and contrast the characteristics of transverse and compressional waves.
Foldables Fold one sheet of lengthwise paper in half.
Foldables Fold into thirds.
Foldables Unfold and draw overlapping ovals. Cut the top sheet along the folds.
Foldables Label the ovals as shown.
Foldables Construct a Venn Diagram As you read the chapter, list the characteristics unique to transverse waves under the left tab, those unique to compressional waves under the right tab, and those characteristics common to both under the middle tab.
Reviewing Main Ideas 1 Waves • Waves carry energy from place to place without transporting matter. • Transverse waves move particles in matter at right angles to the direction in which the waves travel. • Compressional waves move particles back and forth along the same direction in which the waves travel. • The speed of a wave equals its wavelength multiplied by its frequency.
Reviewing Main Ideas 2 Sound Waves • Sound waves are compressional waves produced by something vibrating. • The intensity of sound waves is measured in units of decibels. • You hear sound when sound waves reach your ear and cause parts of the ear to vibrate.
Reviewing Main Ideas 3 Electromagnetic Waves and Light • Electromagnetic waves are transverse waves that can travel in matter or empty space. • Light waves are electromagnetic waves. • The range of frequencies and wavelengths of electromagnetic waves forms the electromagnetic spectrum. • You see an object when light waves emitted or reflected by the object enter your eye and strike light-sensitive cells inside the eye.
Chapter Review Question 1 Imagine that you are looking through a telescope at an enormous volcano erupting on a distant planet. If this were actually happening, you could see the explosions but not hear them. Why not? PS 4.4, PS 4.4c
Chapter Review Answer Light waves can travel through the empty space between Earth and the distant planet, but sound waves can’t. They need a medium in which to travel. No matter how big the explosions were, it wouldn’t make any sound.
Chapter Review Question 2 Wavelengths of light are expressed in _______, which are billionths of a meter. Answer The answer is nanometers. These are written as nm. PS 4.4
Chapter Review Question 3 What is the term for the complete range of electromagnetic frequencies? Answer The electromagnetic spectrum is the complete range of electromagnetic wave frequencies and wavelengths. PS 4.4a
Chapter Review Question 4 All warm bodies emit a kind of radiation. What kind? A. gamma rays B. infrared waves C. ultraviolet waves D. X rays PS 4.4a
Chapter Review Answer The answer is B. This is what you pick up when you use night vision goggles.
Chapter Review Question 5 Which are the electromagnetic waves with the highest energy, the highest frequency, and the shortest wavelengths? PS 4.4a
Chapter Review Answer The answer is gamma rays. These high-energy rays are so powerful they are used in the food industry to kill bacteria.
Standardized Test Practice Question 1 From the point of view of optics, why is a blueberry blue? • because it absorbs blue wavelengths of light • B. because it reflects blue wavelengths of light • C. because it emits blue wavelengths of light • D. it has nothing to do with wavelengths of light PS 4.4b
Standardized Test Practice Answer The answer is B. Any object is the color it is because it is reflecting those wavelengths back into your eye.
Standardized Test Practice Question 2 If a person is farsighted, then they can see _______. A. all objects clearly B. close objects clearly, but not far off ones C. far off objects clearly, but not close ones D. no objects clearly PS 4.4b
Standardized Test Practice Answer The answer is C. Farsightedness can be corrected by wearing glasses.
