Answer: The correct answer is "The wave will bend or defract".

Explanation:

Diffraction: It is the phenomenon in which the light gets bend around the corner of the aperture or a slit. There is a spreading of the waves as they pass through an aperture.

The wavelength of the wave is comparable or greater than the size of the aperture to observe diffraction. If the wavelength of the wave is not comparable or greater than the size of the aperture then in this case, the diffraction is unnoticeable.

In the given problem, a wave is approaching a barrier that has a small hole at the center. A small hole is aperture here. The wave will bend or defract. The diffraction phenomenon will occur in this case.

Therefore, the correct option is (B).

States that there is an exchange of materials when two objects come into contact with each other
pishuonlain [190]

"Edmond Locard" states that there is an exchange of materials when two objects come into contact with each other.

<u>Explanation:</u>

A French criminologist who was popular as the "Sherlock Holmes of France," the pioneer in forensic science named as Dr. Edmond Locard. He articulated forensic science's fundamental principle "Each touch leaves a trace." This became known as Locard's philosophy of exchange. A Locard hypothesized that each and every time you touch another person, place or object, the result would be an exchange of materials. Burglars, for instance, will leave evidence of their existence behind and take traces with them too.
