"No" it is has only unit (radian) not DF

Approach-

Step 1. formula-   plane angle is the ratio of the lenth of arc and the radius of the circle of which the arc is a part

Step 2. DF of each paramter in the formula, as arc and radius both are a type of length or in other words "both" have dimention of length so their ratio becomes dimensionless.

Answer is "No"

Explanation- EM waves are consist of photons which are "chargeless"  quanta of energy so no deflection in EM field.

Approch to solve the problem above-

step-1   necessary condition for deflection is to feel (acted upon) some force in direction other than direction of motion.

step-2 for EM field to exert force the entity should be having some charge

step-3 entities making up EM waves are photons which are "chargeless"

No charge so No force so No deflection.

Strong actions have courage behind it and courage is derived by clarity of thoughts and conviction.

If you value people on basis of money/assets they possess irrespective of the way they achieved it then people may get encouraged to gather money and assets even by bad means (e.g. corruption) just to gratify their desire of feeling important.

Assuming an exam as the last chance of proving preparation or treating it as last chance for doing something good is the reason of stress other than the peer pressure and desire of recognition from society.

Take an exam just a test, it's not final, life is full of opportunities to do good for society to do good for yourself, to excel in various fields just maintain calm of your mind by considering the calmness above result of all exam and above situation dependent recognition given by society.

Impact of your work on general public on weaker section of the society can be a good indicator of the goodness of your work/deed.

calmness increases efficiency and decisive power.
