This is completely TRUE i am writing this to help students because everyone writes bull answers .... the answer is the creator of the wave mechanical model was Dalton in 1803, Thomson in 1897, Rutherford in 1909 and Bohr in 1913. thank you for reading my correct answer the reference is by the book chemistry the physical setting 2006 edition. your welcome.

What waves are mechanical?
Mechanical wave needs a medium to travel. Examples :- Sound Wave, Seismic Wave etc.
Is a sound wave mechanical or electromagnetic?
Seismic waves are mechanical waves.
What are some common properties of waves that scientists measure?
Amplitude period Rise Time (square wave) Fall Time (Square wave) Duty-Cycle (Square Wave)
Why light travels in a straight line in a given medium?
Yes. Light traveling in the same medium, travels in a straight path. It gets refracted only when it hits obliquely with another medium.In olden days scientists thought light is supposed to travel as a ray. Ray meant continuous passage of tiny particles.As understanding gets evolved now we think that light is an electromagnetic wave(not a mechanical wave).Mechanical wave certainly needs a material medium to get propagated where as the electromagnetic wave can even pass through free space, usually we call as vacuum.Its gets diffracted, that is bent at the edges of obstacles, when it meets such.cii nahh.
What is the passage of an EM wave through a medium?
when EM waves encounter a material medium, they can interact with it in much the same way that mechanical waves do. A mechanical wave transfer energy in two ways. As it travels, the wave moves potential energy from one place to another.
