Why is a spectrum of colors produced when white light passes through a prism?

Answer:

Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum.

The spectrum is produced because different colours of light travel at different speeds in glass.

The spectrum is produced because different colours of light travel at different speeds in glass. Red light is slowed down least by glass and is refracted least. Violet light is slowed down most by glass and is refracted most. As a result, the coloured light spreads out to form a spectrum of white light.

What are the wavelengths of electromagnetic wave in free space that have the following frequencies?

Ne4ueva [31]

Explanation:

Given that,

(a) Frequency, $f_1=4\times 10^{19}\ Hz$

All electromagnetic wave moves with the speed of light. It is given by :

$c=f\lambda$

$\lambda_1=\dfrac{c}{f_1}\\\\\lambda_1=\dfrac{3\times 10^8}{4\times 10^{19}}\\\\\lambda_1=7.5\times 10^{-12}$

(b) Frequency, $f_2=5.5\times 10^{1=9}\ Hz$

All electromagnetic wave moves with the speed of light. It is given by :

$c=f\lambda$

$\lambda_2=\dfrac{c}{f_2}\\\\\lambda_2=\dfrac{3\times 10^8}{5.5\times 10^{9}}\\\\\lambda_2=0.054\ m$

Hence, this is the required solution.

Do wave properties affect wave speed

yawa3891 [41]

Answer:

Nope!

Explanation:

The amplitude of a wave does not affect the speed at which the wave travels. Both Wave A and Wave B travel at the same speed. The speed of a wave is only altered by alterations in the properties of the medium through which it travels.

If We Start With 48 Atoms Of A Radioactive Substance, How Many Would Remain After One Half-life?

balu736 [363]

<span>One half-life produces (1/2) of the decaying substance.

There would still be 48 atoms. But 24 would have thrown off
particles from their nucleuses, and only 24 would still be radioactive.</span>
