1. frequency
2. electromagnetic
3. wave x has a greater amplitude
4. the water is not a smooth surface after the rock is dropped in the pond
thats all im going to help with but its a unit test so you can figure the rest out on your own.

1.The image moves behind the curved mirror
2.Light bends due to the difference in the speed of light in air and glass.
3.Light waves do not require a medium to propagate.
4.The frequency of blue light is greater than that of yellow light, while the speeds of both colors of light are the same.
5.wavelength of the stationary source: 11.25 ft; perceived wavelength: 9.25 ft
6.standing waves
7.the vertical distance from the crest or trough of a wave to the equilibrium
8.0.2 seconds
9.The speed of sound increases as the density of water increases.
10.The speed decreases by 25% because speed and wavelength are directly proportional.
11.The wavelength of the wave increases
12.The frequency remains constant.
13.λA=1/3λB
14.1s and 0s
15.Some film methods allow you to print a picture from anywhere without electricity.
16.Results can be quickly and accurately counted and shared.

here are the last ones that u have to write for
17 - The picture illustrates the reflecting behavior of light, where the image of the mountain and the trees is reflected onto the water.
18 - The relationship between harmonics and resonance frequency in a piano is the harmonic is a higher frequency while the resonance is the frequency of which string vibrates the most when hit.
19 - The wavelength of the wave in the string is much shorter than the wavelength of the wave in the air. The frequency of the wave in the string is much higher than the frequency of the wave in the air.
20 -
Advantage - Online software is cheap and easier, it can also be accessed from anywhere.
Disadvantage - Online software would be easier to steal your ideas, also it would not likely have as many features that you could incorporate into maybe a drawing.
these have not been graded yet, i did not write them myself but i fdid change the writing, please change the wording so u dont get caught, ill come back after it has been graded if i dont forgoet abt it

17. The illustration depicts the phenomenon of light reflection. The image of the mountain and the trees gets reflected on the water surface.
18. The relationship between harmonics and resonance frequency in a piano is that harmonic denotes higher frequency whereas resonance indicates the frequency at which strings vibrate the most when struck.
19. The wavelength of the wave in the string is substantially shorter than the wavelength of the wave present in the air. Additionally, the frequency of the wave in the string is much higher when compared to the wave's frequency present in the air.
20.
Advantage - Online software is affordable, easy to use, and accessible from any part of the world.
Disadvantage - The ideas and intellectual property could be compromised with the use of online software. Additionally, the software may lack advanced features required for tasks such as drawing, etc.
