Agroup is considered incapable of understanding technical training, and thus is denied technical training. this group is then unable to gain employment in technical fields. taking this lack of employment in technical fields as evidence of the group’s inability to understand technical information is a self-fulfilling prophecy. select the best answer from the choices provided t f

True

Explanation:

In a self-fulfilling prophecy, what so ever is believed  by a predictor , itself becomes true due to the behaviour of the predictor.  

For example – if an athlete enters a race with a belief that he/she will loose today then he/she  will play a poor game causing loss predicted

Here in this question, it is already believed that people with inappropriate training will not get the job and this comes true as the predictor itself feels that untrained people are inefficient to take up good work and thus should not be offered jobs

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
