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 :)

Give two examples of stimuli that are conditioned reinforcers but not tokens. Explain why they are conditioned reinforcers, and
m_a_m_a [10]

The conditioned reinforcers known as tokens can be accumulated and traded for different reinforcers.

Any two suitable examples, such as a compliment, an invitation to dinner, the presence of a loved one, or a warm greeting are all suitable examples. These are all conditioned reinforcers since they are connected to stronger reinforcers. They cannot be accumulated and swapped for different backup reinforcers, hence they cannot be considered tokens.

What is backup reinforcer?

Backup reinforce is a reinforcer that serves as the foundation for a conditioned reinforcer. It is a reinforcer in a token system for which tokens can be traded in order to keep their reinforcing properties. For instance, poker chips can be converted into cash at the conclusion of a game of poker. The money serves as a secondary reinforcer in this situation. It is allowed to use any two relevant examples.
