The formula vw=f⋅λ
describes the relationship between the speed of a wave ( vw
), and its frequency ( f
) and wavelength ( λ
).
For example, if a wave has a frequency of 120 Hz and a wavelength of 5m, it would have a speed of 600 m/s.
In one or two sentences, describe what would happen to the frequency of this wave if the wavelength is increased to 10m but the speed stays the same at 600 m/s.
If the wavelength is increased to 10m while the speed stays the same at 600 m/s, the frequency of the wave would decrease.

in two sentences, describe what would happen to the frequency of this wave if the wavelength is increased to 10m but the speed stays the same at 600 m/s.
If the wavelength is increased to 10m while the speed remains constant at 600 m/s, the frequency of the wave would decrease. This is because frequency is inversely proportional to wavelength, so as the wavelength increases, the frequency decreases.
Red tape can be used to repair a broken taillight on a car. In one or two sentences, explain how different colors of light are transmitted, reflected, and absorbed by this kind of tape.
Different colors of light are transmitted, reflected, and absorbed by red tape in a specific way. Red tape primarily absorbs all other colors of light except for red, which it reflects and transmits, giving it its characteristic color appearance.
You want to make a photo album for your friend. In three to five sentences, describe at least one advantage and one disadvantage of choosing a digital photo album rather than a physical one. Analyze a potential solution to the disadvantage.(4 points)
One advantage of choosing a digital photo album is the convenience and portability it offers. With a digital album, you can store hundreds or even thousands of photos in one device, making it easy to carry and access anywhere. Additionally, digital albums allow for easy sharing and duplication of photos through various platforms.
However, a disadvantage of digital photo albums is the reliance on technology and the possibility of data loss. If the device or storage medium fails or gets lost, the photos may be permanently deleted or inaccessible. To mitigate this risk, it is important to regularly back up the digital album to multiple locations, such as cloud storage or an external hard drive, ensuring that the photos are preserved even if the original device is lost or damaged.
Furthermore, in cases where physical albums have a sentimental value, a potential solution could be to create a hybrid approach. One could print select photos from the digital album and create a physical album alongside the digital one, allowing for the preservation of memories in both formats.
