Energy is inversely proportional to the wavelength of a wave. Which would have the GREATEST energy? A wave with a wavelength of ______ meters.

Houses with carpet are much quieter than houses with tile or hardwood floors because of sound wave

Visible light represents a very small portion of the electromagnetic spectrum. Radiation to the left in the image, such as microwaves, has a longer wavelength than visible light. Radiation to the right has a shorter wavelength than is observable.

Which radiation has a higher frequency than visible light?

Refraction or the bending of waves takes place when a light wave changes

The hammering on a train track is often heard twice by workers farther down the track; first as the sound travels through the steel and second as the sound travels through the air. This suggests which graph is true?

Assume the light wave directed at the paper is white light and the paper contains pigments that absorb the wavelengths of red-orange-yellow-blue-indigo-violet. What color will the paper appear to human eyes?

Although you can see the pencil, it appears broken in the glass of water. This is because

What type of wave is being described?

Bella notices when she looks through a magnifying glass objects appear to be larger. A magnifying glass is used to magnify, or makes objects look larger. It uses a special lens mounted in a frame and usually has a handle. What type of lens does a magnifying glass have?

Based on the images seen here, identify which phase of matter would transmit sound waves the fastest, and why?

________________ transmission is the basis for most communication today. All radio and TV, as well as many other ways humans communicate, like wireless internet, use this technology.

Which pair of properties apply to both sound and electromagnetic waves?

Holly reads a website article about the effects of ultraviolet rays. The article includes both positive effects: triggers vitamin D production in body, helps some skin conditions, and helps improve mood and depression - and negative effects: causes sunburn and skin cancer, damages eyes, ages skin, weakens plastics, and fades colors. What conclusion is she likely to draw from this information?

What type of signal is utilized by the GPS satellite?

A Wi-Fi hotspot is an area with an accessible wireless network. The term is most often used to refer to wireless networks in public areas like airports and coffee shops. Some are free and some require fees for use, but in either case they can be handy when you are on the go. Just like cellphones and televisions, wi-fi works by utilizing ______________ to transmit signals and data.

A boat moves up and down as water waves pass under the boat. If the amplitude of the wave gets bigger, then

Any wave of any kind will change direction when it encounters an obstacle. This bending is called

A __ lens is sometimes called a converging lens because it ___.

Which graph BEST represents the relationship between wave amplitude and wave energy?

Note: amplitude is the independent variable.

Which wave carries the most energy?
