Answer:
572.3 nm
Explanation:
= refractive index of the oil film = 1.48
= thickness of the oil film = 290 nm
= wavelength of the dominant color
m = order
Using the equation
For m = 0
= 1716.8 nm
For m = 1
= 572.3 nm
For m = 2
= 343.4 nm
Hence the dominant color wavelength is 572.3 nm

Answer:
Work done against gravity in lifting an object becomes potential energy of the object-Earth system. The change in gravitational potential energy, ΔPEg, is ΔPEg = mgh, with h being the increase in height and g the acceleration due to gravity.
