Education / What Occurs When An Object Takes In A Wave As The Wave Hits It? by restorapos(m): 9:14am On Jan 24
When an object interacts with a wave, several phenomena can occur depending on the nature of the wave and the properties of the object. The key concepts involved in this interaction include reflection, transmission, absorption, and diffraction. Here's a brief overview:

Reflection: The wave may bounce back from the surface of the object. This occurs when the wave encounters a boundary that does not allow it to pass through easily. The angle of reflection is typically equal to the angle of incidence.

Transmission: The wave pass through the object, especially if the object is transparent or the wave has enough energy to penetrate it. The degree to which the wave is transmitted depends on the properties of both the object and the wave.

Absorption: The object may absorb some or all of the energy carried by the wave. This absorption can lead to an increase in the internal energy of the object, causing it to heat up.

Diffraction: The wave may bend around the edges or obstacles of the object, leading to a change in the direction of the wave. This phenomenon is more pronounced when the wavelength of the wave is comparable to the size of the object.

The specific behavior of the wave-object interaction depends on factors such as the type of wave (e.g., sound, light, water waves), the frequency and wavelength of the wave, and the physical properties of the object (e.g., density, transparency, composition).
