A 5 A Light Of Wavelength 7 500 Nm Is Incident Upon A Double Slit Arrangement In Which The Distance Between The Sl 1 (53.39 KiB) Viewed 26 times

a 5. (a) Light of wavelength 7. = 500 nm is incident upon a double-slit arrangement in which the distance between the slits d=1.00 x 10m. On a screen a distance La 1.00 m from the slits, a bright line is observed at y = 1.50 mm from the center of the screen as seen in Figure 7. What order of bright line is this (value of m)? (b) Parallel rays of light of wavelength 655 nm fall upon a pair of slits that are 1.57 x 10%m apart. The interference pattern is focused on a sereen 2.00 m from the slits. Find i. the angle for the third maximum and ii. the distance of this maximum from the center of the screen. (a) Cahaya dengan jarak gelombang i = 500 nm di tujukan ke slit dua celah di mana jarak di antara slit adalah d = 1.00 x 10' m. Atas skrin yang berjarak L = 1.00 m dari sfit, cahaya cerah di lihat pada y = 1.50 mm dari tengah skrin seperti dalam Rajah 7. Apakah nilai m untuk jalur cerah ini? (b) Pancaran cahaya selari dengan jarak gelombang 655nm mengenai sepasang slit berjarak pisah 1.57 x 10 m. Corak inteferen di tumpukan kepada skrin yang berjarak 2.00m dari slit-slit. Carikan i.
