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. (2 point

If the wavelength is increased to 10m but the speed of the wave remains the same at 600 m/s, the frequency of the wave would decrease because there are now fewer complete wavelengths passing through a given point in one second.

Different colors of light are transmitted, reflected, and absorbed by red tape based on the principles of selective reflection and absorption. The tape selectively reflects and absorbs all other colors of light except for red, which it transmits, making the tape appear red when light interacts with it.

One advantage of choosing a digital photo album is that it offers unlimited storage capacity, allowing you to include a large number of photos without worrying about physical space limitations. Another advantage is the ability to easily share the album with others through digital platforms or email, allowing for convenient distribution. However, a disadvantage of a digital photo album is that it may lack the tactile and sentimental value of a physical album, which can be cherished and displayed physically. A potential solution to this disadvantage is to create a digital album and also print a selection of the photos to be placed in a physical album, combining the convenience of digital with the sentimental value of a physical keepsake. This way, both the sentimental value and the convenience of sharing and storing photos digitally can be achieved.
