Answer: Diffraction occurs when waves interact with a gap.
Diffraction occurs in any type of wave—mechanical or electromagnetic.
Explanation:
The phenomenon of light to bend around a small obstruction in its path is known as diffraction. Diffraction occurs for any type of waves- transverse or longitudinal i.e. for mechanical or electromagnetic waves.
When the medium changes- refraction occurs. Waves reflect back from a barrier. Diffraction occurs when the wavelength of the wave is comparable to the size of the gap. The wave bends around the corners of the gap.

Newton's second law shows that there is a direct relation ship between force and acceleration . the grater force that is applied on a object of given mass the more the accelerate. for example doubling the force in the object doubles it's acceleration.
When hot tea is mixed to chilled coke, tea loses heat and coke gains heat. Thus, tea cools down but coke gets heated. Because it is liquid and liquid does not totally cool down to the ambient temperature, it and the iced drink will eventually reach the same temperature.
