What is the maximum number of diffraction maxima that can be observed for a double-slit experiment with a slit separation of 0.1 mm and light of wavelength 500 nm?
Step 1: Identify the given values. The slit separation (d) is 0.1 mm and the wavelength of light (λ) is 500 nm.
Step 2: Convert the units to be the same. Convert 0.1 mm to nanometers: 0.1 mm = 100,000 nm.
Step 3: Use the formula for the maximum number of observable maxima, which is d/λ.
Step 4: Substitute the values into the formula: 100,000 nm / 500 nm.
Step 5: Calculate the result: 100,000 / 500 = 200.
Step 6: The maximum number of observable maxima is 200.
