Part 1: Emission Background Energy level diagram for hydrogen 50mm 121.6 mm 1026m 973 mm UV 410.1 4340 nm 6563 1. On the energy level diagram above, which transitions emit light in visible region of the electromagnetic spectrum? (ii) Label these transitions with the appropriate color. (iii) Which of these emits the highest energy photons? (ix). Which emits the lowest energy photons? 2. On the energy level diagram above, which transitions emit light in ultraviolet (UV) region of the electromagnetic spectrum? (ii) Why can't we see these? 3. (1) On the energy level diagram above, which transitions emit light in the infrareri (IR) region of the electromagnetic spectrum? (ii) Why can't we see these?

Answer 1

Part 1: Emission Background Energy level diagram for hydrogen → IR region → Visible region > UV region UV 410. 14340 nm 6563 1. On the energy level diagram above, which transitions emit light in visible region of the electromagnetic spectrum? (ii) Label these transitions with the appropriate color. (iii) Which of these emits the highest energy photons? (ix.Which emits the lowest energy photons? 2. On the energy level diagram above, which transitions emit light in ultraviolet (UV) region of the electromagnetic spectrum? (ii) Why can't we see these? 3. () On the energy level diagram above, which transitions emit light in the infrareri (IR) region of the electromagnetic spectrum? (ii) Why can't we see these?

1)

(i)

Higher energy to n = 2 transitions will fall under visible region.

6 → 2;

5 → 2;

4 → 2 ;

3 → 2

(ii) 656.3 nm ---- RED; 486.1 nm ---- BLUE; 434 & 410.1 nm ---- VIOLET

(iii) n= 6 → n= 2 transition emits highest energy photons (larger the gap between energy levels)

(iv) n = 3 → n = 2 transition emits lowest energy photons (smaller the gap between energy levels)

2) (ii) & 3) (ii):

The human eye consists rods and cones cells of the retina and are only sensitive to the wavelengths of the visible region lights and cannot able to sense beyond UV & IR regions.
