Differentiate between Scalar quantity and Vector quantity and give two examples each​

Explanation:

Scalar Quantity

1 . Scalar quantity has only magnitude, but no

direction.

2. Every scalar quantity is one dimensional.

3. Any change in scalar quantity is the

reflection of change in magnitude.

4. Scalar quantity cannot be resolved as it has

exactly same value regardless of direction.

5. Any mathematical operation carried out

among two or more scalar quantities will

provide a scalar only. However, if a scalar is

operated with a vector then the result will b(

a vector.

6. Few examples of scalar quantity: length,

mass, energy, density, etc.

Vector quantity

1 . Vector quantity has both magnitude and

direction.

2. Vector quantity can be I -D, 2-D or 3-D.

3. Any change in vector quantity can reflect

either change in direction or change in

magnitude or changes in both.

4. Vector can be resolved in any direction using

sine or cosine of the adjacent angle.

5. Result of mathematical operations between

two or more vectors may give either scalar or

vector. Dot product of two vectors gives only

scalar; while, cross product or summation or

subtraction results in a vector.

6. Examples of vector quantity: displacement,

velocity, acceleration, force, etc.

it is the second option.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
