    Answer: Angle 59 degree

    Explanation: Given that the

    n1 = 1.0

    n2 = 1.5

    Øi = 35 degree

    From Snell law, which says that

    n1/n2 = sinØ1 / sinØ2

    Substitute all the parameters into the formula

    1/1.5 = sin 35/sinØ2

    Cross multiply

    Sin Ø2 = 1.5 sin35

    SinØ2 = 1.5 * 0.573 = 0.860

    Ø2 = sin^-1 (0.860)

    Ø2 = 59.36 degree

    Ø2 = 59 degree (approximately)

    It has angle 59 degree when passing from air to glass
