We move the full reflect plate from 40 to 20cm, and we transfer the equation (X1-X2)= N λ/2 to λ=(X1-X2)2/N, and we can put X1=40cm, X2=20cm, and the N is 14 then we can get λ= 2.85714286. the real microwave wavelength, we use λ=c/f, which c is the velocity of the light( 3*10^8m/s), also we have the information of the transmitter of f is 10.5GHz which shows in the P3, from the equation we can get the λ is 0.02857142857143.
P2(the data graph of the wave that move from 40cm to 20cm, and there are 14 peaks in the wave). X1(cm) X2(cm) N λ (cm) 40 20 14 2.86 P3( the information of the transmitter) Answers to questions 1. When it maximum that means two beams of light waves peaks are meat each other, the minimum of the wave means two beams of light waves are opposite. 2. No, because when I lean on the table, every part of the experiment is change in the same ration, so the whole equipment is still not change, if we change any single
element inside the equipment, it will change the Maxima. 3. Because the visible light has higher frequency, it’s more accurate than the microwave. Conclusion The experiment is helping us to know how to calculate the wavelength through different methods, and we proved the equation of λ is true, and also we know the actual number of microwave wavelength.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
