Answer:
constructive λ = 130 m
destructive λ = 260 m
Explanation:
a) the expression for constructive interference is that the difference in amino is equal to a multiple of the average wavelength
AQ - BQ = 2m λ/ 2 m = 0, 1, 2, ...
Where
AQ = 130 +50 = 180 m
BQ = 50 m
To find the smallest wavelength let's use m = 1
180 - 50 = 2 1 λ/ 2
λ = 130 m
b) for destructive interference
AQ –BQ = (2m + 1) λ/2
The smallest value is for m = 0
130 = λ / 2
λ = 260 m
Answer:
Convection is equal to the conduction plus fluid flow.
Explanation:
Convection is a mode of heat transfer that requires the movement of the molecules of the medium from one point to another. It takes place majorly in fluids (liquids and gases). While conduction is a process by which heat is transfered by the vibtation of molecules of a medium at their possitions, thereby colliding with other neighbouring molecules to transmit heat.
Before convection could occur, there must be conduction of heat by the molecules of the medium which causes their motion. According to the kinetic molecular theory, any molecule of the medium close to the source of heat conducts heat, becomes less dense and thus moves so that its initial position would be occupied by another denser molecule. This continous process generate convection or convectional current. Therefore, convection is as a result of conduction and fluid flow because a molecule must first conduct heat before it moves.
