<h3>What is a Vector ?</h3>A vector is an object that has both a magnitude and a direction
- Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction.
- The direction of the vector is from its tail to its head.
- Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight.

Answer:
a.96cm
b.77cm
Explanation:
Highest intensity,=19cm
Lowest intensity,=29cm
48cm is the distance for half-wave, wavelength =48cm*2=96cm
b. From a, above we know that half-wavelength is 48cm
Also, the distance of known maximum is 29cm
Next maximum is calculated as:
The next maximum will occur at 77cm
