A. A light wave moves through glass (n=1.5) at an angle of 25°. What angle will it have when it moves from the glass into air (n
torisob [31]

PART A)

By Snell's law we know that

n_1sin i = n_2 sin r

here we know that

n_1 = 1.5

i = 25 degree

n_2 = 1

now from above equation we have

1.5 sin25 = 1 sin r

r = 39.3 degree

so it will refract by angle 39.3 degree

PART B)

Here as we can see that image formed on the other side of lens

So it is a real and inverted image

Also we can see  that size of image is lesser than the size of object here

Here we can use concave mirror to form same type of real and inverted image

PART C)

As per the mirror formula we know that

\frac{1}{d_i} + \frac{1}{d_o} = \frac{1}{f}

\frac{1}{d_i} + \frac{1}{60} = \frac{1}{20}

d_i = 30 cm

so image will form at 30 cm from mirror

it is virtual image and smaller in size
