Some text here about the topic of discussion

​Explain how objects appear to have color.

​We see color based on the wavelength of visible light waves. Different wavelengths appear as different colors. An object can absorb or reflect wavelengths. The color or wavelength that is reflected is the color of the object that we see. All other wavelengths were absorbed by the object. Example: if you see a blue object, it means the color (wavelength) for blue has been reflected and the other wavelengths have been absorbed by the object.

​Explanation: When the length is changed, it will vibrate with a different frequency. Shorter straws will produce sound waves with higher frequency and therefore higher pitch.

Multiple Choice

Which figure above is the loudest? Explain.

• Figure 1 is the loudest because it has a higher amplitude. Additionally, the amplitude is greater when the particles of the medium are squeezed closer together in each compression and spread farther apart in each rarefaction.

• Figure 2 is the loudest because it has a higher amplitude. Additionally, the amplitude is greater when the particles of the medium are squeezed closer together in each compression and spread farther apart in each rarefaction

Multiple Choice

• Figure 1 has the highest pitch because it has the highest wave frequency

• Figure 2 has the highest pitch because it has the highest wave frequency

Multiple Choice

Which figure above is carrying the most energy? Explain.

• Figure 1 is carrying the most energy because higher frequency and higher amplitude = higher energy transfer

• Figure 2 is carrying the most energy because higher frequency and higher amplitude = higher energy transfer

Multiple Choice

Which figure above has the highest frequency? Explain.

• Figure 1 has the highest frequency because it has the shortest wavelength. Short wavelength = High Frequency

• Figure 2 has the highest frequency because it has the shortest wavelength. Short wavelength = High Frequency

Multiple Choice

Each picture below shows a ray of light interacting with a different surface. One surface is a shiny metal, one surface is clear plastic, and one surface is painted black.

Identify which Rays of Light illustrate Refraction, Reflection and Absorption.

• Surface A is Reflection; Surface B is Refraction; Surface C is Absorption

• Surface A is Reflection; Surface B is Absorption; Surface C is Refraction

• Surface A is Refraction; Surface B is Absorption; Surface C is Reflection

• Surface A is Refraction; Surface B is Reflection; Surface C is Absorption

Multiple Choice

Each picture below shows a ray of light interacting with a different surface. One surface is a shiny metal, one surface is clear plastic, and one surface is painted black.

Identify the surfaces as shiny metal, clear plastic, or painted black. Explain your answer for each.

• Surface A is the clear plastic because it would reflect light. Surface B is the painted black surface because black objects absorb all wavelengths therefore no wavelengths are reflected or pass through. Surface C is most likely the shiny because the ray of light passes through the plastic but is refracted due to the change in speed of the wavelength because of the change in the medium.

• Surface A is the shiny metal because it would reflect light. Surface B is the painted black surface because black objects absorb all wavelengths therefore no wavelengths are reflected or pass through. Surface C is most likely the clear plastic because the ray of light passes through the plastic but is refracted due to the change in speed of the wavelength because of the change in the medium.
