    Answer:

    Angle of incidence is given as

    i = 63 ^o

    Explanation:

    As per law of refraction of light we know that

    n_1 sin i = n_2 sin r

    here we know that

    angle of refraction is “r”

    r = 35^o

    now we have

    1 sin i = 1.553 sin35

    sin i = 0.89

    i = 63 ^o
