O1.0 mm di question4 1 pts the light spectrum of a star shows the peak wavelength emitted by thel star to be at 400 nm. what is the surface temperature of the star? 9875 k o 4625 k 7250 k 8750 k

the surface temperature of star is 7250 K

Explanation:

Given data

wavelength = 400 nm

to find out

the surface temperature of star

solution

we will apply here wiens law formula that is given below

wavelength × temperature  = 0.0029 m-k    1

put the value of wavelength in equation 1 so we get temperature here

wavelength × temperature  = 2900000 nm-k  

temperature = 2900000 / 400

temperature = 7250 K

so the surface temperature of star is 7250 K

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
