An energy inefficient incandescent light bulb uses a hot filament to produce a continuous spectrum. the temperature of the filament is typically about 2853 k. at what wavelength (in nanometers)is the light bulb the brightest?

So the wavelength of light is 1015.7 nm

Explanation:

From Wein's displacement law, we can write the following formula;

here, is the wavelength of maximum radiation in meters

T is the absolute temperature (in Kelvin) for maximum radiation

K is the constant has a value of

Given here,  T = 2853 K

And we need to find  

Putting the values in formula

when the chinese communist party took power in 1949, it began to build new di and levees to hold the yellow and yangtze rivers back.

i do not know the answer bro
