Already Graded A+
Light from two closely spaced stars cannot produce a steady interference
pattern due to - 🧠 ANSWER ✔✔incoherence
In the double slit experiment, fringes are more widely spaced when
illumination is with monochromatic (single color) - 🧠 ANSWER ✔✔longer
wavelength light
When waves from a pair of closely spaced slits arrive in phase - 🧠
ANSWER ✔✔a bright fringe is produced
, Interference colors in a soap bubble is evidence that the soap film - 🧠
ANSWER ✔✔has two reflecting surfaces and thin [both of these]
In wave optics - 🧠 ANSWER ✔✔we make a distinction between coherent
and incoherent sources of light.
An incoherent source of light - 🧠 ANSWER ✔✔lacks a specific direction and
