The fact is a beam of light needs a medium such as smoke to be seen, the fact is beams of light is observe effect, the light off the sun is isotropic and it is a fact it is not opaque.
That is strange, I have a laser, I can not see the laser beam in natural light or in the dark , the frequency is beyond my visual range , however when I blow smoke from my cigarette, the laser interacts with the smoke and I can see the laser beam.
It is not a myth I own a laser and have tried this several times.

And if the frequency was inside your visual range?
Please look at any object in your room, do you see any diagonal paths of light, it is whole.
There you go proven.
It depends on how you define 'diagonal'. Which plane you are referring to as the vertical and the horizontal. So yes, I see more diagonal than vertical or horizontal.
You think a student is a troll for questioning the integrity of the knowledge been presented to him?
No, you questioning this is actually very good of you. But to ignore certain facts, and respond with a very vague/random response completely tangential to the argument you are presented with is rather infuriating to try and have a discussion with. I will now wrap this up:
Here we have a spaceship with a mirrored floor and roof. Now: Δt′=cd=c2L For the person in the spaceship, this is the change in time. note this is a model, and we are tracking the photon from the clock As above, the time frame for the person in the space ship is as we expect it. distance/velocity is time. Now for the observer outside the spaceship. Again this is a model
According to our observer, the distance D has changed compared to the person in the spaceship. Using pythagoras we can calculate this: D2=L2+(2x)2 Where x is the change in the x axis due to v x=vΔt So by this logic Δt′=c2L, Δ=c2h. Therefore, L=2cΔt′ and D=2cΔt Substituting these values into the first equation: (2cΔt)2=(2cΔt′)2+(2vΔt)2 As such:
It depends on how you define 'diagonal'. Which plane you are referring to as the vertical and the horizontal. So yes, I see more diagonal than vertical or horizontal.
No. There is no contradiction. They all agree on speed, but disagree on time. Therefore they disagree on distance too.
Distance can equal 1 if time equals 1 Or distance can equal 2 if time equals 2
Yes , the speed of light in a vacuum is an invariant, we both can agree that light travelling 1m in a vacuum is a constant, but we both have to agree that time is an invariant.

Nope, wrong.
If the frequency of the light were outside your visual range, it'd be an IR or UV light. Doesn't matter if it's passing through smoke or what, you wouldn't be able to see it.
Just doesn't reflect off of the thinly dispersed gases in the air, hence why you don't see the light unless it's passing through a smoke or pointed directly at your eyes. It's just directional hence why you don't see it most of the time. Light from the sun, however, is widely dispersed and hence reflects off just about everything around us.

Ok, so then you can tell me the frequency of white light can you?

Seriously...
White light is made up of a mixture of different wavelengths of light. Combining all the different components of the visible spectrum into one light source creates a light that appears to be white.

Pretty sure that Year 7s know this.
Obviously I already know the answer, so in the space between your eyes and any object can you tell me what frequency of light you observe?
