Ultimately, the question “Why is the sky blue?” is not just about physics—it is about the spirit of inquiry. It shows how even the simplest observation can lead to profound truths.
In fact, it’s the result of sunlight being scattered when it strikes the air molecules in the atmosphere. Sunlight is made up of – literally – all the colours of the rainbow, and the complex physics of how light interacts with molecules means shorter-wavelength blue light is more strongly scattered than red light.

In physics, tensors are often a mixture of several vector spaces and several dual spaces. It also makes sense to sort both kinds as the tensor product isn’t commutative. Type (p,q) Tensors Definition: A tensor of type of with contravariant and covariant components is an element (vector) of By (1) this tensor is linear in all its components.
