Abeam of yellow monochromatic light passes from liquid water (n=1.333) into ice (n=1.309). in the liquid water, the beam makes an angle of 40.0 with the normal. when the beam is traveling in the ice, what angle does it form with the normal?
40.7
39.3
41.2
68.5

Did you get the answers to the Light Unjt 4 quiz? If so can you please comment them with the written out answers. Thanks!

40.7

Explanation:

na*sin(theta a)=nb*sin(theta b)

1.333*sin(40)=1.309*sin(theta b)

0.857/1.309=sin(theta b)

0.65=sin (theta b)

sin^-1 (0.65)=40.7

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes
