Want this question answered?
1. Sound waves 2. Light wave
well hear is more than 2 sound waves, waves in a slinky, tsunami waves, vibrations in gases, internal-water waves, ultra sounds, earthquake P-waves.
Yes they can. It's called destructive interference. When 2 sound waves converge on each other and the waves are 180 degrees out of phase then they will destructively interfere and the net effect will be the negation of both waves so you hear nothing.
No. The 2 types of mechanical waves are transverse waves & longitudinal waves
2. overtones
When 2 or more straight lines meet...the point where they meet is called the point of intersection
A place where two routes meet are called Super-2.
A place where two routes meet are called Super-2.
if you're talking about 2 triangles that overlap, then yes and they are called overlapping triangles. XD
2 Lines in the same plane that do not meet are parallel. If 2 lines are in different planes and do not meet, then they are called skew lines.
there where a polygon meet that 2 segments is called ''vertex''
The waves and kinks in a sheep's wool are called crimp. Sheep's wool has between 2 and 30 waves or kinks to the inch.
When two primary colours overlap, it forms 'White Light'.
the edge
vertex
1 line i guess
It is called the Vertex
