फ्रेसनल्स बायाप्रिझम मध्ये (λ) तरंगलांबीची किंमत कशावर अवलंबून असते ? / In Fresnel's Biprism, the value of wavelength (λ) depends upon
1)दोन संलग्न उगमास्थानातील अंतर / The distance between two coherent sources
2)फ्रिंजची रुंदी / The fringe-width
3)स्लिट व दूरदर्शकाची नेत्रकाच यातील अंतर / The distance between slit and eyepiece of telescope
4)वरील सर्व / All of the above✓ Correct
In Fresnel's biprism experiment, the wavelength of light depends on fringe width, distance between coherent sources, and distance between slit and eyepiece, as all these variables are mathematically related in the fringe width formula.
