Question

Which statement related to particle and wave properties of matter is correct? a. Interference patterns are observed when a wave passes through a barrier with two slits. b. Particles exhibit diffraction while waves do not. c. A wave travels straight through a slit. d. Particles interfere constructively and destructively whereas waves do not.

Answer 1

Answer:

a. Interference patterns are observed when a wave passes through a barrier with two slits

Explanation:

Interference is a situation where two waves superimpose to form a new wave of a different amplitude. This amplitude can be greater, same or lower.

the diagram attached below shows the movement of a wave through a barrier with two slits.

you can notice the portions of the wave that overlap. This overlapping of waves is the interference.

Thus, option A is correct.

The other options however,  are not correct. as shown below:

Option B is wrong as waves exhibit diffraction (it is diffraction of the light wave that produces the rainbows we see in the sky)

Option C is wrong as waves do not travel straight through slits always.

Option D is wrong as waves can also interfere constructively and destructively.
