Answer 1

First question : This is a bit tricky. Yes, it DOES depend on the wavelength of the light wave, but, all other things being equal, it is an INVERSE dependence on wavelength, rather than a direct dependence. So, with that understanding, the answer is TRUE. See the next, parenthetical paragraph for factors involved other than the wavelength.

[The brightness depends upon the square of the amplitude --- in wave terms --- or on the NUMBER of photons passing through perpendicular unit area per unit time, but it also depends on the fact that an INDIVIDUAL photon has energy E = h nu = h c / lambda, where ' nu ' is the (circular) frequency and ' lambda ' is the wavelength. Technically, "Brightness" is the amount of energy crossing perpendicular unit area per unit time, so it involves the PRODUCT of the FLUX of photons (number crossing unit area per unit time) and the energy of those individual photons. So, all other things like the flux of photons being equal, the brightness of light DOES depend on the wavelength, albeit INVERSELY dependent on it.]

Second question : C n=1, n=2, n=3, etc. These numbers are the radial quantum numbers of the principal energy levels in the atom.

Live long and prosper.

Answer 2

False. The wavelength of light determines its colour. The amplitude of the wave corresponds to brightness.

Answer 3

the cost of light (electromagnetic radiation) is continuing at 3.0 x 10^8 m / sec. in a vacuum. c = velocity of light = 3.0 x 10^8 m / sec. f = frequency in Hz wL = wavelength in meters ----------------------------- the dating is: c = f x wL If the frequency will advance, the wavelength would desire to shrink in length such that "c" remains consistent. occasion: c = one million,six hundred,000 Hz x 187.5 m = 3.0 x 10^8 m /sec. c = 27,000,000 Hz x eleven.one million m = 2.997 x 10^8 m / sec. c = one hundred,000,000 Hz x 3.0 m = 3.0 x 10^8 m / sec. --------------------------- Amplitude has not something to do directly with the two frequency or wavelength, besides the shown fact that it does impact intensity of the wave. Your answer: not one of the above terrific regards

Answer 4

FALSO

wavelength determines color of the light wave I believe

and principal energy levels?

that would be C

Answer 5

The brightness of light would be Energy per meter squared and would not depend on frequency. Unless of course the light is out of the visible spectrum and you cannot see it.

Answer 6

False. Artificial light depends on watts and whats making the light. The wavelength determines what 'color' you see....... or can't see.
OK?................... OK.
