Why Does an Object Emit Every Color of Light?

AI Thread Summary
An object emits every color of light due to the principles of black body radiation, where it radiates energy across a spectrum of wavelengths. The intensity of emitted light varies, peaking at a specific wavelength depending on the object's temperature. The discussion highlights that objects can emit light across the spectrum if their electrons can be excited by various wavelengths. This means that the emitted light includes all colors, but with varying intensities. Understanding these principles clarifies why objects emit a range of colors.

1. Homework Statement

Can anybody explain this picture?
My guess is: the object emits every wave-length but it emits more wavelengths or more light from the colour that the peak is at. Is this correct? Why does the object emit wvery colour?

I've inserted a copy of the image to make it viewable without following a link.

@Drizzy: Look up black body radiation or black body spectrum.
 
I have read about it but no website has an answer to my question
 
My guess is thatn objectsens out wavelengths that correspond to the light that makes the elctron excited. So if we have an object that can get excitet from every wavelength then it is going to sens out light with every wavelength
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
