Can two or more quantities have same dimensions?
In general, if the dimensions are same, the quantities do represent the same physical content. Like work and energy have the same dimensions and represent inter-convertible quantity. They perhaps do not represent the same physical content. These two quantities represent the same quantity – same meaning and content.
What is the unit of refractive index *?
Unit of refractive index (μ) will be the ratio of the unit of speed of light in vacuum(c) to the speed of light in the given medium(v). As you can see, the unit of refractive is 1, which means the refractive index is just a number without any unit.
Which pair of physical quantity does not have SI unit?
Answer Expert Verified (c) Tension and surface tension is the pair which have physical quantities not having the same dimentional formula…….
Which all physical quantities have same dimensions?
Note: The dimension of quantities which are interchangeable into one another have exactly the same dimension. For example, energy can transform from one form to another. So each type of energy whether it is kinetic energy or nuclear energy, they all have the same dimension.
Can a quantity have unit but no dimensions?
A quantity cannot have units until it has dimensions. A quantity that has dimensions must have units. Yes a quantity have units but still be dimensionless for example,unit of angle is radian ,but it is a dimensionless quantity. A dimensionless quantity may have unit.
