A would be the wavelength, C would be a crest, D would be the amplitude, leaving B which is the trough.

Answer: B. B

Explanation:

The trough is B because it is the "minimum" amplitude of a wave since amplitude is D which is the displacement of wave from its initial position. The minimum value of the amplitude will be at B which is the trough.

Note that the maximum value of the amplitude will be the crest which at C.

A red laser with a wavelength of 670 nm and a blue laser with a wavelength of 450 nm emit laser beams with the same light power.

E=hf C=wavelength*F

E=hC/wavelength

E=(6.626*10^-34)*(3.00*10^8)/670*10^-9

E=(6.626*10^-34)*(3.00*10^8)/450*10^-9

Two point charges exert a 5.00 N force on each other. What will the force become if the distance between them is increased by a

weeeeeb [17]

Answer:

force becomes one - ninth

Explanation:

According to Coulomb's law in electrostatics, two charges can exert a force of attraction or repulsion on each other which is directly proportional to the product of two charges and inversely proportional to the square of distance between them.

Here both the charges remains same but the distance is variable.

So, we can say that

$F \alpha \frac{1}{d^{2}}$ .... (1)
