Question 2 of 20
2. Question1 point(s)
Light passes through a diffraction grating ruled at 1000 lines per cm and the same wavelength of light also passes through two narrow slits 0.5 mm apart. Both situations produce intensity maxima and minima on a screen.
Which statement about the separation of the maxima on the screen and the sharpness of the maxima is correct?CorrectIncorrect
Question 3 of 20
3. Question1 point(s)
The diagram shows an experiment which has been set up to demonstrate two-source interference. Microwaves of wavelength λ pass through two slits S1 and S2.
The detector is moved from point O in the direction of the arrow. The signal detected decreases until the detector reaches point X, and then starts to increase again as the detector moves beyond X. Which equation correctly determines the position of X?CorrectIncorrect
Question 4 of 20
4. Question1 point(s)
A student attempts to show the interference of light using two identical green LEDs. Which statement explains why the experiment will not succeed?CorrectIncorrect
Question 5 of 20
5. Question1 point(s)
A stationary wave is set up on a stretched string, as shown.
Which statement about the points on the string is correct?CorrectIncorrect
Question 6 of 20
6. Question1 point(s)
Monochromatic light is incident on a diffraction grating and a diffraction pattern is observed.
Which line of the table gives the effect of replacing the grating with one that has more lines per metre?
number of orders of diffraction visible angle between first and second orders of diffraction A decreases decreases B decreases increases C increases decreases D increases increasesCorrectIncorrect
Question 7 of 20
7. Question1 point(s)
The diagram shows a stationary wave on a string at two instants of maximum vertical displacement.
The frequency of the wave is 12 Hz. What is the speed of the wave?CorrectIncorrect
Question 8 of 20
8. Question1 point(s)
A loudspeaker emitting sound of frequency f is placed at the open end of a pipe of length l which is closed at the other end. A standing wave is set up in the pipe.
A series of pipes are then set up with either one or two loudspeakers of frequency f. The pairs of loudspeakers vibrate in phase with each other. Which pipe contains a standing wave?
Question 9 of 20
9. Question1 point(s)
In a double-slit experiment the distance between the fringes, on a screen, was too small to measure. What would increase the distance between the fringes?CorrectIncorrect
Question 10 of 20
10. Question1 point(s)
Source S emits microwaves with a constant amplitude. The microwaves hit a metal screen P and are reflected. A stationary wave is formed between S and P. The wavelength of the microwaves is much smaller than the distance between S and P.
A detector Q is moved at a slow, constant speed from S to P. What happens to the amplitude of the signal detected by Q?CorrectIncorrect
Question 11 of 20
11. Question1 point(s)
A pattern of waves was observed without being able to view the source of the waves. The pattern is represented in the diagram.
What can cause this pattern?CorrectIncorrect
Question 12 of 20
12. Question1 point(s)
Wave generators at points X and Y produce water waves of the same wavelength. At point Z, the waves from X have the same amplitude as the waves from Y. Distances XZ and YZ are as shown.
When the wave generators operate in phase, the amplitude of oscillation at Z is zero. What could be the wavelength of the waves?CorrectIncorrect
