Answer:
Explanation:
Wgen the sound is emitting from two speakers, the sound waves interfere each other. the locations at which the destructive interference occurs, we get no sound and the locations where constructive interference occurs, the sound occurs at that locations.
Answer:
2.11 m
Explanation:
<u>Given data</u>
h=6.626×(plank constant)
L=45.7 pm
n=n2-n1
n=5-1
n=4
<em>where,</em>
<em>n2=5</em>
<em>n1=1</em>
<u>To find:</u>
E=?
λ=? (Wavelength)
<u>solution</u>
The energy stored in an electron at a specified level is given by;
E=×÷8m..........(1)
<em>m=mass of electron(9.1×</em>)
<em>l=length of box</em>
<u>To find E</u>
putting the value of given data in eq(1)
E=9.41×
<u>To find λ</u>
λ=hc/E............................(2)
c=3×(speed of light)
putting the value in eq 2 to find wavelength
λ=2.11 m
<u></u>
<u>Note:</u>
There is a chance in calculation error. but the method is correct to solve the problem.
Answer:
it maybe correct
Explanation:
You can feel an increase of pressure on your eardrums. ... The deeper you go under the sea, the greater the pressure of the water pushing down on you
Amplitude is the height frequency is how many waves produced in amount of time and wavelength is the distance between waves so it’s amplitude
