I put them together but idk, for the second point I said the material/object the mug is placed on


That's correct

For the mug qustions
Could you put volume of liquid


I think it had to be about the mug itself apart from the material so the answer was something like the colour

I don't think so because similar could suggīest greater or larger, don't worry I said greater haha

Haha ok but in the textbook it said similar not same so thats why i put it
For the infrared and microwaves question I said they both travel at the speed of light in a vacuum and they are both transverse waves.
Would that get me 2 marks?

Thats what I put down. My friends said it was wrong. 25000/something= 340m/s. Are you certain?

I can't remember the details of the question to be honest with you, but I did double-check and I didn't see anything wrong with it? I can't really remember it tho

for the rural one could i have put that it would be expensive connecting to the national grid so the amount of electricity generated wouldn't be worth it?

Same I said there's a small community in the area so the costs of all the transformers and cables wouldn't be worth it..?
mobile phones - microwaves
infrared- optical fibre

similarities :

transverse waves
they travel at the same speed through a vacuum.

No. The full 1 mark will be given only if you wrote Cosmic Microwave Background Radiation.


I think they would accept that as that is pretty much the answer but you only forgot one word

could you say bend instead of spread out for the diffraction question ?

Yes they are both properties :smile:

The waves spread out

It had a glass base...glass dont have free electrons? Does it?🤔
For the control variables question would the same room/surrounding temperature be correct?
What was the answer for the waves diffracting relating to the size of the insect??

no it doesn't, only metals do.

Mobile phones infrared?
Microwaves I had as transmission signals?

what about the last question about the convection current of the coffee?
Do you think I'd get the mark for saying that both waves travel at 3 x 10^8 but I didn't write in a vacuum? :frown:

waves diffract same as/equal to size of insect for max diffraction

What did you have for that then? I knew glass is a poor conductor, but how else can you explain energy transfer by conduction in a glass? there must be electrons free to move?
