While Rebecca at her locker she can hear students coming from around the corner. Which wave interaction explains why she can hea
Ronch [10]

Answer:

Diffraction

Explanation:

Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.

Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.

hope this helps :)

A victim of foreign body airway obstruction become unresponsive. what is your first course of action?
Anna11 [10]
Answer:
Use a head tilt (tilting the head backward) and chin lift to prevent the tongue from obstructing the upper airway, and look for the foreign body that is causing the obstruction.

Explanation.
The backward head tilt and chin lift will prevent the tongue from obstructing airflow.
If the foreign object can be seen and removed, do so. Usually, it is not wise to use the fingers unless the foreign object is visible and accessible.

The next step is to perform CPR because the patient is unresponsive.
