Physical Science
| Question | Answer |
|---|---|
| A disturbance that transfers energy from place to place is called a | Wave |
| The material through which a wave travels is called a | Medium |
| Waves are created when a source of energy causes a medium to | Vibrate |
| Waves are classified according to | How they move |
| The highest parts of a transverse wave are called | crests |
| Waves that move the particles of the medium parallel to the direction in which the waves are traveling are called | Longitudinal waves |
| Waves on the top of a pond or lake are | Transverse Waves |
| The maximum distance that the particles of a medium move from the rest position is the | Amplitude of the wave |
| The distance between two corresponding parts of a wave is the wave’s | Wavelength |
| Wave frequency is measured in units called | Hertz |
| The speed of a wave is its wavelength multiplied by its | Frequency |
| Which of the following affects the speed sound waves traveling through air? | How often the sound is repeated |
| When a wave hits a surface through which it CANNOT pass and bounces back, it undergoes | Reflection |
| The bending of waves due to a change in speed is called | Refraction |
| The bending of waves around the edge of a barrier is known as | Diffraction |
| The interaction between two waves that meet is called | Inteference |
| Waves combine to make a wave with larger amplitude in a process called | Constructive Interference |
| Waves combine to produce a smaller or zero-amplitude wave in a process called | Destructive Interference |
| What occurs when vibrations traveling through an object match the object’s natural frequency? | Resonance |
| Waves produced by earthquakes are called | Seismic Waves |
| Which waves have some electrical properties and some magnetic properties? | Electromagnetic Waves |
| Electromagnetic waves can transfer energy without a(n) | Medium |
| What is transferred by electromagnetic waves? | electromagnetic radiation |
| How much faster than sound are electromagnetic waves? | one million times faster |
| In 1905, Albert Einstein suggested that light energy travels in tiny packets or particles called | Photons |
| All electromagnetic waves have the same | Speed |
| Which electromagnetic waves have the longest wavelengths and lowest frequencies? | Radio Waves |
| Visible light has a higher frequency than | Infrared Rays |
| The range of electromagnetic waves placed in a certain order is called the | electromagnetic spectrum. |
| The electromagnetic waves with the highest frequencies are called | Gamma Rays |
| Microwaves can be used to | Heat Food |
| When a police officer uses radar for speed control, the officer is using what kind of electromagnetic waves? | Radio Waves |
| The process that uses radio waves and magnetism to produce images of tissues in the human body is called | radiation treatment. |
| Visible light can be separated into the various colors of the visible spectrum to form a(n) | Rainbow |
| Which of the following is true of ultraviolet rays? | They help your body produce vitamin D. |
| An instrument used to view different colors of light produced by each type of light bulb is called | Spectroscope |
| Which type of light bulb glows when a filament inside it gets hot? | Incandescent |
| Which light bulbs are coated on the inside with a powder? | Fluorescent |
| Which type of light bulb is commonly used in advertising signs and decoration? | neon |
| If something vibrates one million times per second, it has a frequency of | Megahertz |
| What kind of waves do cellular telephones use to transmit and receive signals? | Microwaves |
| A material that reflects or absorbs any light that strikes it is | Opaque |
| Clear glass, water, and air are examples of what kind of material? | Transparent |
| What happens when parallel rays of light hit a smooth surface? | regular reflection |
| What occurs when parallel rays of light hit a rough or bumpy surface? | Diffuse Reflection |
| When the surface of a mirror curves inward, like the inside of a bowl, it is called a | Concave Mirror |
| The bending of light rays as they enter a new medium is called | Refraction |
| What happens when light passes from air into water? | The light slows down |
| A curved piece of glass or other transparent material that is used to refract light is called a(n) | Lense |
| What happens when white light strikes a black object? | No light is reflected |
| How would a tomato look under blue light? | The tomato would still appear red |
| The primary colors of light are | red, orange, yellow, green, blue, and violet. |
| What instruments use lenses or mirrors to collect and focus light from distant objects? | Telescopes |
