- Calculate the wavelengths of the following objects. A 75 kg athlete running a 3.0-minute mile: m Earth (mass = 6.0 ×× 1027 g) moving through space at 2.5×104 m/s: m3. Suppose we wish to do a double-slit experiment with a beam of smoke particles of mass 10-9 g moving at 1 cm/s. Assume we can construct a double slit whose separation is about the same size as the particles. Estimate the separation between the fringes if the double slit and the screen were on opposite coasts of the United States.If I have a light with a frequency of 5 x 10^14 what is the wave length in nm?

Two field mice are separated by 0.010 m. From a distance of 201 m, the eagle sees them as one unresolved object and dives toward them at a speed of 16 m/s. Assume that the eagle's eye detects light that has a wavelength of 550 nm in vacuum. How much time passes until the eagle sees the mice as separate objects? t = i6. In a polarizer-analyzer combination, 90.0% of the light intensity falling on the analyzer is absorbed. Determine the angle between the transmission axes of the polarizer and analyzer.
