A blackbody curve represents the relation between <u>intensity of radiation with wavelength.</u>
Here in this curve we can see that all ideal blackbody radiates almost all wavelength of radiations and these radiations are of different intensity.
here intensity will be maximum for a given wavelength of radiation and the relation of this wavelength with the temperature of the object is given by Wein's law
It is given by
now if we increase the temperature the maximum intensity for which wavelength is given will shift to the left.
Using this all we can also compare the temperature of two blackbody for which radiation graph is given to us.
Ans: Time <span>taken by a pulse to travel from one support to the other = 0.348s

Explanation:
First you need to find out the speed of the wave.
Since
Speed = v =
Where
T = Tension in the cord = 150N
μ = Mass per unit length = mass/Length = 0.65/28 = 0.0232 kg/m
So
v =
= 80.41 m/s
Now the time-taken by the wave = t = Length/speed = 28/80.41=0.348s
