Describe how waves superpose on each other using specific examples from two types of waves.
anastassius [24]

Answer:Towhen two waves if nearly same amplitude and same wavelength interfere with each other that time a new wave is formed with a different amplitude this phenomena is known as superposition. If two waves interfere with each other in same phase that time amplitude of resultant wave   wave is greater than the component waves and this type of interference is known as constructive interference. And when waves suprpose in opposite phase that time amplitude of resultant wave is less than the component waves and this type of interference is known as destructive interference.

Example: light waves, water waves, sound waves etc
