Answer:
Hemoglobin bound to oxygen absorbs blue-green light, which means that it reflects red-orange light into our eyes, appearing red. That's why blood turns bright cherry red when oxygen binds to its iron. Without oxygen connected, blood is a darker red color.
Hope this helps :)

8+6.5+2x=52
52/2=8+6.5+x
26=8+6.5+x
26-8-6.5=x
11.5=x
Answer:
Slit width is 0.109 mm
Solution:
As per the question:
Wavelength of the light, 
Distance from the screen, D = 5.6 m
Bright band in the center, 2x = 8.1 cm
x = 4.05 cm
Now,
To calculate the slit width, w:
From the diffraction:
For small angle:
≈ 
Also
Thus
Substituting appropriate values in the above eqn:
w = 0.109 mm
