12 - waves 2

Question 1

principle of superposition

Answer 1

when two similar types of waves meet at a point the resultant displacement at that point is equal to the sum of the displacements of the individual waves

Question 2

superposition

Answer 2

overlap of two waves at a point in space

Question 3

interference

Answer 3

superposition of two progressive waves from coherent sources to produce a resultant wave with a displacement equal to the sum of the individual displacements from the two waves

Question 4

constructive interference

Answer 4

superposition of two waves in phase so that the resultant wave has a greater amplitude than the original waves

Question 5

destructive interference

Answer 5

superposition of two waves in antiphase so that the waves cancel each other out and the resultant wave has smaller amplitude than the original waves
