Hi is a light photon consist of all the wavelengths in a spectrum?

Homework Statement Using quantum mechanics, what happens when a photon of light hits glass? Homework Equations Momentum= Mass x velocity The Attempt at a Solution I am not sure of my answer but suffice to say the following: Assuming the collision between the photon particle and those in the...

The thing is air isn't a substance with a fixed shape to begin with. And I deliberately didn't answer your question as it's irrelevant to what I am trying to get at.

What happens to the dimensions of air when the plunger is depressed as per question.?

How can I when I don't even understand what you are talking about here...

Apologies but you don't seem to make much sense at all.

When the plunger is depressed, only the vertical dimension is reduced (correct me if I am wrong here) while the other 2 dimensions remain unchanged. As such, going by the definition of a shape , one of which is "a 3D space that is defined by the length of its dimensions', we can conclude that...

A cylinder will transform into a disc if it's vertical dimension is reduced sufficiently. 'cylinder' and 'disc' are two different shapes altogether. Likewise the above example when the air is compressed...

The issue here is 'shape'...By definition "shape is defined by a set of parameters, one of them being the length of the dimensions in space..." Hence, by using the term 'shrinking' , you would have effectively altered the shape of air as its dimensions would have been altered.

By "shrinking away from the walls" wouldn't you in effect have changed the shape of air also? Also here we are just concerned with air per se and not about other matters. And we all know that air having no fixed shape allows for the plunger to move down (option 3). Similarly, air having no...

Answers and their interpretation are always debateble as in this case. Perhaps I was thinking too deeply but then again that's how a great mind works. Correct me if I sound wrong...

The concept of the interrelationship between volume, pressure n temperature as espoused in Boyle's law is beyond the scope of Year 3 s.

Boyle's law speaks of volume, temp n pressure-concepts which are beyond the scope of Year 3s. Imagine for once, if air had a fixed shape here, you wouldn't be able to push down the plunger, would you?

If air had a fixed shape here, you wouldn't be able to push down the plunger, would you? We need to read deeper in order to fully understand what's happening on the surface. This is not asking for too much for a simple question like this. Anyway it's also another option presented in the array...

Please share with me your opinion as I am not sure if my explanation is accurate.
