Final answer:
The statement is true. Constructive and destructive interferences are indeed the two types of interference, where waves either reinforce or cancel each other.
Step-by-step explanation:
The statement 'The two types of interference are constructive and destructive interferences' is true. Interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude. Interference effects can be observed with all types of waves, such as light, radio, acoustic, and surface water waves.
Constructive interference occurs when the phase difference between the waves is such that they reinforce each other, resulting in a wave of greater amplitude. Conversely, destructive interference occurs when the two waves are out of phase and partially or entirely cancel each other out, resulting in a wave of reduced amplitude.
