An inverted image can be seen in a convex mirror:A. Under no circumstancesB. When the object is very far from the mirrorC. When the object is at a distance equal to the radius of curvature of the mirrorD. When the distance of the object from the mirror is equal to the focal length of the mirror

To find the critical angle of water, follow these steps:

• Understand that the critical angle occurs when light moves from a medium with a higher refractive index (like water) to a medium with a lower refractive index (like air).
• Use Snell's Law, which states that n₁ sin(θ₁) = n₂ sin(θ₂). Here, n₁ is the refractive index of water, n₂ is the refractive index of air, θ₁ is the angle of incidence, and θ₂ is the angle of refraction.
• Recognize that at the critical angle, θ₂ is 90 degrees, meaning sin(θ₂) = 1.
• Rearrange Snell's Law to find the critical angle θ_c: sin(θ_c) = n₂/n₁.
• Substitute the values for n₁ (approximately 1.33 for water) and n₂ (approximately 1.00 for air) into the equation.
• Calculate θ_c using the inverse sine function: θ_c = arcsin(n₂/n₁).
• Finally, evaluate the expression to find the critical angle in degrees.
