    Difference
In summary, a simple harmonic wave and a stationary wave differ in that the amplitude of the former changes with time while the latter remains constant. Stationary waves are formed by the superposition of two waves traveling in opposite directions, resulting in constructive and destructive interference at different points. Although they are a type of destructive interference, stationary waves still exist due to the superposition of the two waves.

i want to know the basic difference between simple harmonic wave and stationary wave.

and also why stationary wave is type of distructive interference.
if stationary wave is a type of distructive interference so why stationary wave exist.

A stationary wave is composed of two waves traveling in opposite directions. They add together to create positive and negative interference at each point.

but stationary wave form by destructive interference why??
if there is destructive interference the wave should not to be form??

The basic difference is that the amplitude of one changes with time and that the other does not (hence stationary). Why do you think the waves traveling in opposite directions only have destructive interference?

What is the difference between SW and SHW?

The main difference between SW (Software) and SHW (Software Hardware) is that SW refers to the instructions and programs that run on a computer or device, while SHW refers to the physical components that make up the device, such as the processor, memory, and storage.

Can SW function without SHW?

No, SW cannot function without SHW. In order for a computer or device to run software, it needs the necessary hardware components to process and execute the instructions. Without SHW, the software would have no way to run or operate.

Can SHW function without SW?

Yes, SHW can function without SW. While software is necessary for users to interact with and utilize the capabilities of hardware, the hardware itself can still function and perform basic tasks without any software. For example, a computer can still turn on and display basic information without any software installed.

What are some examples of SW and SHW?

Examples of SW include operating systems, applications, and games. Examples of SHW include processors, RAM, hard drives, and graphics cards. Some devices, such as smartphones and tablets, have both SW and SHW components.

Are SW and SHW interchangeable terms?

No, SW and SHW are not interchangeable terms. They refer to different aspects of a computer or device and serve different functions. While they work together to enable the use of technology, they are distinct and cannot be used interchangeably.
