If ${\mu }_1$ and ${\mu }_2$ both are increased by same amount, the ray will suffer total internal reflection

If ${\mu }_1$ and ${\mu }_2$ both are increased by same amount, the ray will suffer refraction and angle of refraction will be less than $90^{\circ }$.

If ${\mu }_1$ and ${\mu }_2$ both are doubled, ray will suffer total internal reflection

If ${\mu }_1$ and ${\mu }_2$ both are doubled, ray will suffer refraction and angle of refraction will be less than $90^{\circ }$.
