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 :)

What needs to happen for recessive traits to be observed in an organism?
ANEK [815]

Answer:

For recessive traits to be observed, dominant genes must be absent.

Explanation:

There are 3 possibilities for the genes: AA, Aa, aa.

in both AA and Aa, there is a dominant gene present. If a dominant gene is present, it will always show the dominant trait.

In aa, there is no dominant gene present, and there are only recessive genes. Because of this, the recessive trait is observed!
