Question

The formula for both correction for curvature and refraction

Answer 1

Answer:

Explanation: Correction for curvatureis 0.07849 d2. Therefore, here 0.07849*(2.48)2 = 0.483 m.

Curvature in the surface of a component will have an effect on the shape of the ultrasonic beam. ... The "correction" value is the change in amplitude needed to bring signals from a curved surface measurement to the flat surface or DAC value.

For light, refraction follows Snell's law, which states that, for a given pair of media, the ratio of the sines of the angle of incidence θ1 and angle ofrefraction θ2 is equal to the ratio of phase velocities (v1 / v2) in the two media, or equivalently, to the indices of refraction (n2 / n1) of the two media.
