Refraction is the bending of a wave disturbance as it passes at an angle from one medium into another
I got it keep it bucks worth u this it tooooo muchhhhhhh
Answer: A medium is any substance or region through which a wave is transmitted. The speed of a wave is dependant on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency (speed = l * f).
Answer:
22.17 degree
Explanation:
n = 1.52
Angle of incidence, i = 35 degree
Let the angle of refraction is r.
use the Snell's law
n = Sin i / Sin r
Sin r = Sin i / n = Sin 35 / 1 .52
Sin r = 0.37735
r = 22.17 degree
Thus, the ray is refracted at an angle of 22.17 degree.
Answer:
Explanation:
The resistance of a wire depends on the length of the wire and the area of crossection of wire.
resistance is directly proportional to the length of the wire
and inversely proportional to the area of crossection of the wire.
So, to decrease the resistance, length should be decreased and the area of crossection should be increased.
