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 :)
<span>the student could identify the catalyst by noticing the substance that makes a chemical reaction go faster. It will be written in a chemical equation.
Example of Catalyst :
- A corosion process of an iron will be faster if it exposed to Oxygen
- A burning process will be a lot of faster if it mixed with oil.</span>
You may find them floating in the cytosol. These floating ribosomes make proteins that will be used inside the cell. Other ribosomes are found on the endoplasmic reticulum.
