| Question | Answer |
| Reverberation | repeated echoes of sound |
| Echo | reflected sound |
| Frequency | number of wavelengths that pass a given point in 1 second |
| Pitch | human perception of frequency |
| Infrared Waves | electromagnetic waves given off by warm bodies |
| Ultraviolet Waves | electromagnetic waves that come from the sun, and damage the skin |
| Visible Waves | electromagnetic waves that give off lights of different colors that people see |
| Cochlea | changes sound to electrical signals and sends them to the brain |
| Intensity | perceived as the loudness of sound |
| Cornea | the transparent layer forming in the front of the eye |
| Retina | back part of the eye that contains the cells that respond to light |
| Rods and Cones | rods are used to see in dim light, and cones are used to see color |
| How 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. |
| How 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. |
| What is the Type of Wave that Carries Sound? | The type of wave that carries sound is a compressional wave. |
| How do Humans Perceive the Intensity of Sound? | Humans perceive the intensity of sound by the perception of loudness. |
| What is the Intensity of Sound that Humans can Tolerate? | The intensity of sound that humans can tolerate are less than 120 dB. |
| Why 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. |
| How 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. |
| What types of Electromagnetic Waves are Microwaves? | The type of electromagnetic wave that is a microwave is a radio wave. |
| What 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. |
| Explain 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. |
| How 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. |
| Your 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. |
| Light Travels as what Wave? | Light travels as transverse waves. |
| What is the Relationship Between Brightness and Intensity? | The relationship between the brightness and intensity is that the intensity determines the brightness of the light. |
| Compare 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. |
| Incident 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. |
