This is not multiptle choice Sound: Now click the Sound tab.

Part A
On the Sound tab, investigate briefly all the phenomena you explored with water waves above and describe any similarities in your results for sound. Specifically, describe

wave pattern as seen on the screen
shape and amplitude of the graph
effect of frequency on wavelength
effect of frequency on velocity
pattern with two sources
wave pattern with a single-slit barrier

Question 3
Light: Now click the Light tab.

Part A
On the Light tab, once again investigate briefly all the phenomena you explored with water and sound above. Describe any similarities in your results for light. Specifically describe

wave pattern as seen on the screen
shape and amplitude of the graph
effect of frequency on wavelength
effect of frequency on velocity
pattern with two sources
wave pattern with a single-slit barrier

Sound waves

The wave pattern that i observed in sound waves are longitudinal wave patterns.

The mathematical graph function looks like is a sine function graph. The pattern that i observed in the amplitude of the wave is longitudinal wave pattern

When you increase the frequency of the sound waves the wave moves faster but the wavelength becomes shorter. The higher the frequency results in higher the pitch of the sound.

If you increase the frequency the velocity of the sound wave remains constant for all valuses of frequencies.

i am currently completing this assigment. i am not usre if the answer are correct but i tried my best  

I also got this from course hero it's your choise to put the one you want.

The wave pattern is identical to the pattern of the water. The graph is the same as the water except the wave height isn’t as big. Increasing the frequency increases the wavelength. Increasing the frequency also increases the velocity of the waves by a lot. With two sources the waves pass through each other. The wave pattern with a single slit barrier is the same as the water pattern.

Explanation:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

its first and third is your answer i did the qustion the fourth isnt right
