Interference of light Explain why the separation of the two slits is 2h. If the two beams have paths that differ by exactly one wavelength λ in Young’s double slit, do they add constructively to make a bright interference region, or destructively to make a dark one? If the two beams have paths that differ […]
Set the frequency of the wave and then measure the wavelength and speed. Explain does wave speed really equal frequency times wavelength?
Physics Lab: Waves on a String Waves are a familiar part of everyday life. You have probably seen water waves and waves on a string. You hear sound waves and see light waves. Waves have a wavelength, λ, a frequency, f, and a speed, v. These three quantities are related by: v = fλ In […]
What is the major difference between the wave theory proposed by Huygens and that proposed by Young and Maxwell?
Principals of Light Questions What is the major difference between the wave theory proposed by Huygens and that proposed by Young and Maxwell? 5 marks Briefly: What is meant by rectilinear propagation of light? What natural phenomenon depicts this? 3 marks Approximately at what speed does light travel at? 1 mark Draw a diagram to […]
Describe what happens to light when it shines on a medium.
This lab uses the Bending Light simulation from PhET Interactive Simulations at University of Colorado Boulder, under the CC-BY 4.0 license. Learning Goals A.Describe what happens to light when it shines on a medium. B.Explain light direction changes at the interface between two media and what determines the angle. C.Describe the effect of varying wavelength […]
What happened to the patterns when you increased the wavelength of the light?
Part 2. Single Slit Diffraction If the viewing screen is far away, the rays heading for any point on the screen are essentially parallel. Consider the waves emanating from the upper half and lower half of the slit. Destructive interference, a dark fringe, occurs if the pathdifference from any point in the upper half of […]
Describe the actions that could have been taken to reduce the effects of loading and wave action in this case.
Consider a 9 hold bulk carrier, loaded with alternate holds empty and, others full of Iron Ore, sailing on an ocean passage, in storm conditions. Explain how the wavelength is produced naturally and how various wavelengths would have differing effects on the hull structure in this loaded condition. Describe the actions that could have been […]
