Flashcards do conjunto (28)
- 1Reverberationrepeated echoes of sound
- 2Echoreflected sound
- 3Frequencynumber of wavelengths that pass a given point in 1 second
- 4Pitchhuman perception of frequency
- 5Infrared Waveselectromagnetic waves given off by warm bodies
- 6Ultraviolet Waveselectromagnetic waves that come from the sun, and damage the skin
- 7Visible Waveselectromagnetic waves that give off lights of different colors that people see
- 8Cochleachanges sound to electrical signals and sends them to the brain
- 9Intensityperceived as the loudness of sound
- 10Corneathe transparent layer forming in the front of the eye
- 11Retinaback part of the eye that contains the cells that respond to light
- 12Rods and Conesrods are used to see in dim light, and cones are used to see color
- 13How do the Different Types of Matter Affect the Speed of Sound?The different types of matter affects the speed of the sound because the speed of sound travels faster in solids than in liquids, and faster in liquids than in gases.
- 14How does Temperature Affect the Speed of Sound?Temperature affects the speed of sound because the speed of sound through a material increases as the temperature of the material increases.
- 15What is the Type of Wave that Carries Sound?The type of wave that carries sound is a compressional wave.
- 16How do Humans Perceive the Intensity of Sound?Humans perceive the intensity of sound by the perception of loudness.
- 17What is the Intensity of Sound that Humans can Tolerate?The intensity of sound that humans can tolerate are less than 120 dB.
- 18Why do Theaters have Curtains and Carpets?Theaters have curtains and carpets because soft materials such as curtains and carpets absorb the energy of the sound.
- 19How is Pitch Related to the Frequency of Sound Waves?Pitch is related to the frequency of sound waves because sounds with low frequencies have low pitch, and vice versa.
- 20What types of Electromagnetic Waves are Microwaves?The type of electromagnetic wave that is a microwave is a radio wave.
- 21What is the Relationship Between the Frequency and Wavelength of Light?The relationship between the frequency and wavelength of light is that the shorter the wavelength is, the higher the frequency is, and vice versa.
- 22Explain the Relationship Between the Wavelength, Frequency, and Energy of Waves in the Electromagnetic Spectrum.The relationship between the wavelength, frequency, and energy of waves in the electromagnetic spectrum is that the energy and frequency of a wave goes left to right in the electromagnetic spectrum, while the wavelength of a wave is reversed for the electromagnetic spectrum.
- 23How is the Speed of Light Affected by the Type of Matter?The speed of light is affected by the type of matter because the speed of light travels faster in gases than in liquids, and faster in liquids than solids.
- 24Your Body makes Vitamin D with the Help of what Type of Light Wave?The body makes vitamin D with the help of ultraviolet light waves.
- 25Light Travels as what Wave?Light travels as transverse waves.
- 26What is the Relationship Between Brightness and Intensity?The relationship between the brightness and intensity is that the intensity determines the brightness of the light.
- 27Compare and Contrast Light Waves and Sound Waves.Light and sound waves are similar because they both carry energy, but they are different because sound waves are slower than light waves.
- 28Incident Rays Always Equals what?Incident rays always equals to reflected wave, so the smaller angle of the reflection wave would also make the incident wave decrease, and vice versa.
