- Notice that these 2 waves are OUT OF PHASE. When they hit they screen they both hit at the different relative positions, one at the bottom of a crest and the other coming out of a trough. Thus their amplitudes SUBTRACT.
- E'tibor bering, bu 2 ta to'lqin FAZADAN CHAQADI. Ular ekranga urilganda, ikkalasi ham har xil nisbiy pozitsiyalarga toqnashadi, biri tepalikning pastki qismiga, ikkinchisi esa yuqoriga chiqadi. Shunday qilib, ularning amplitudalari AYRILADI.
- How much farther did the red wave have to travel?
- Qizil to'lqin qancha masofani bosib o'tishi kerak edi?
- Exactly – ONE HALF OF A WAVELENGTH
- Aynan - to'lqin uzunligining bir yarimi
- The call this extra distance the PATH DIFFERENCE. The path difference and the ORDER of a fringe help to form another pattern.
- Ushbu qo'shimcha masofani YO'LLAR FARQI deb nomlang. Yo'l farqi va chekka TARTIBI boshqa naqsh hosil qilishga yordam beradi.
- The dark fringes you see on either side of the central maximum are multiple wavelengths from the bright central. And it just so happens that the multiple is the ORDER.
- Siz markaziy maksimalning har ikki tomonida ko'rgan qorong'u chiziqlar yorqin markazdan bir nechta to'lqin uzunliklari. Va shunday bo'ladiki, ko'plik TARTIB bo'ladi.
- P.D. = (m+1/2)
- Destructive)
Path Difference - Summary - For CONSTRUCTIVE INTERFERENCE or MAXIMUMS use:
- For DESTRUCTIVE INTERFERENCE or MINIMUMS use:
- Where “m”, is the ORDER. Refer to slides 6 and 11.
