Worked Solution & Example Answer:1 (a) Figure 1 shows how the visible spectrum of white light is shown on a screen - Edexcel - GCSE Physics - Question 1 - 2022 - Paper 1
Step 1
Which of these is the best piece of equipment to produce the white light?
Answer
The best piece of equipment to produce white light is a ray box (Option A). A ray box is designed specifically to emit light and often contains a light source, which enables the production of white light that can be directed through a prism to produce a spectrum.
Step 2
Which colour is seen between yellow and blue in the spectrum on the screen?
Answer
The color seen between yellow and blue in the visible spectrum is green (Option C). This can be derived from the arrangement of colors in the spectrum, where yellow transitions to green before reaching blue.
