What is the critical angle of benzene is 1.5

To calculate the critical angle of benzene, we need to gather some additional information. The critical angle is typically associated with the phenomenon of total internal reflection, which occurs when light passes from a medium with a higher refractive index to a medium with a lower refractive index.

However, the critical angle is not a property specific to a substance like benzene. Instead, it depends on the refractive indices of benzene and the surrounding medium. So, to determine the critical angle of benzene, we need to know the refractive indices of benzene and the medium it is in contact with.

Once you have the refractive indices of benzene and the surrounding medium, you can calculate the critical angle using the formula:

Critical angle = arcsin(n2 / n1)

Where:
- n1 is the refractive index of the medium through which light travels before reaching the interface with benzene.
- n2 is the refractive index of benzene.

By substituting the given refractive indices into the formula, you will be able to calculate the critical angle.
