Critical angle of glass is θ1 and that of water is θ2 The critical angle for water and glass surface would be (μg = 3/2, μw = 4/3).

Question

Critical angle of glass is θ1 and that of water is θ2 The critical angle for water and glass surface would be (μg = 3/2, μw = 4/3). (A) less than θ2 (B) between θ1and θ2 (C) greater than θ2 (D) less than θ1

As wμg = 9/8 < aμw < aμg ∴ θ > θ2 > θ1

Q. Critical angle of glass is $θ_{1}$ and that of water is $θ_{2}$ The critical angle for water and glass surface would be $(μ_{g} = 3/2, μ_{w} = 4/3)$ .

less than $θ_{2}$

between $θ_{1}$ and $θ_{2}$

greater than $θ_{2}$

less than $θ_{1}$

As $^{w} μ_{g} = 9/8 <^{a} μ_{w} <^{a} μ_{g}$
$∴ θ > θ_{2} > θ_{1}$

Q. Critical angle of glass is θ1​ and that of water is θ2​ The critical angle for water and glass surface would be (μg​=3/2,μw​=4/3).

less than θ2​

between θ1​and θ2​

greater than θ2​

less than θ1​
