Edexcel gcse (9 1) physics sp5 light and the electromagnetic spectrum test with mark scheme 16 17-key points
![Question 1(b)(iii)
angle of incidence < critical angle [1 mark]
no TIR / light only refracted / moves out of the
glass [1 mark]
thus reflected light weaker (or similar) [1
mark]](https://image.slidesharecdn.com/edexcelgcse9-1physicssp5lightandtheelectromagneticspectrumtestwithmarkscheme1617keypoints-170214101109/85/Edexcel-gcse-9-1-physics-sp5-light-and-the-electromagnetic-spectrum-test-with-mark-scheme-16-17-key-points-3-320.jpg)
![Question 2(b)(i)
Correct statement [1 mark]
f of blue > f of red [1 mark]
blue bends more than red [1 mark]](https://image.slidesharecdn.com/edexcelgcse9-1physicssp5lightandtheelectromagneticspectrumtestwithmarkscheme1617keypoints-170214101109/85/Edexcel-gcse-9-1-physics-sp5-light-and-the-electromagnetic-spectrum-test-with-mark-scheme-16-17-key-points-6-320.jpg)
![Question 2(b)(ii)
Colours bend differently / have different
speeds / different refraction etc. [1 mark]
Do not focus on a single point [1 mark]](https://image.slidesharecdn.com/edexcelgcse9-1physicssp5lightandtheelectromagneticspectrumtestwithmarkscheme1617keypoints-170214101109/85/Edexcel-gcse-9-1-physics-sp5-light-and-the-electromagnetic-spectrum-test-with-mark-scheme-16-17-key-points-7-320.jpg)

- 2. Question 1(b)(ii) The density of the glass coating is less than the density of the glass core. Remember
- 3. Question 1(b)(iii) angle of incidence < critical angle [1 mark] no TIR / light only refracted / moves out of the glass [1 mark] thus reflected light weaker (or similar) [1 mark]
- 6. Question 2(b)(i) Correct statement [1 mark] f of blue > f of red [1 mark] blue bends more than red [1 mark]
- 7. Question 2(b)(ii) Colours bend differently / have different speeds / different refraction etc. [1 mark] Do not focus on a single point [1 mark]
- 8. Question 3 Vocabulary check: transmitted = passes absorbed = stopped
