White lightincident on a diffraction grating produces rainbows of diffracted light. What is the width of the first-order rainbow on a screen behind the grating?
A triple-slit experiment consists of three narrow slits, equally spaced by distance and illuminated by light of wavelength . Each slit alone produces intensity on the viewing screen at distance.
Consider a point on the distant viewing screen such that the path-length difference between any two adjacent slits is. What is the intensity at this point?
What is the intensity at a point where the path-length difference between any two adjacent slits is?
In a single-slit experiment, the slit width is times the wavelength of the light. What is the width of the central maximum on a screen behind the slit
A 4.0-cm-wide diffraction grating has 2000 slits. It is illuminated by light of wavelength . What are the angles (in degrees) of the first two diffraction orders?
You need to use your cell phone, which broadcasts an signal, but you're behind two massive, radio-wave absorbing buildings that have only aspace between them. What is the angular width, in degrees, of the electromagnetic wave after it emerges from between the buildings
