Answer:
Option B
0.3 m/s2 South
Explanation:
Acceleration, where v and u are final and initial velocities respectively, t is the time taken
Substituting 14.1 m/s for v, 17.7 m/s for u and 12 s for t then
Since this is negative acceleration, it's direction is opposite hence 0.3 m/s2 South
In dispersion Phenomenon the bending of light depends on the formula
here A is angle of prism
now here we know that value of refractive index will inversely depends on the wavelength of light
so here we will have maximum value of refractive index for violet light as we can see that its wavelength is minimum.
Since its refractive index is maximum so it will bend by maximum angle
so here correct answer will be
<em>Violet light will bend a lot.</em>
