Answer:
So visible wavelength which is possible here is
416 nm and 693.3 nm
Explanation:
As we know that for normal incidence of light the path difference of the reflected ray is given as
so here we can say that for maximum intensity condition we will have
so we have
now for visible wavelength we have
for N = 1
for N = 2
for N = 3
The answer is D)Hydroponic plants are grown without soil. Nonhydroponic plants are grown in soil.
Answer:
The answer to the question is A.
Explanation:
The definition of moment is Force multiplied the distance to the point of interest.
So the external moment at point O is equal to ⇒ EMо= F×d
Knowing the definition of moment of inercia (I) and a newtonian Force ( m.a)
We can say that te moment of the externals force at point O is EMо= IGa
Because the rotation of a body in a inmovil point is implicated by the moment of inercia an the action of the gravity in that moment.
Answer:
Explanation:
Mechanical waves and electromagnetic waves are the types of waves we have. The major difference between this type of waves is that, while mechanical waves requires material medium for its propagation, electromagnetic waves does not require material medium for its propagation.
Example of mechanical waves are waves produced by a ripple tank.
Example of an electromagnetic waves are the electromagnetic spectrum which includes radio waves, infrared waves, visible light, ultraviolet rays etc... This waves are produced naturally without any medium compare to mechanical wave.
