Answer:
Explanation:
Power of defective eye = (1 / near point )+ (1 / lens-retina distance )
1 / .0198 m = (1 / near point )+ (1 / .02 m )
= 50.50 = (1 / near point )+ 50
0.50 = 1 / near point
near point = 1 / .5 = 2m
= 200 cm .
for near point at 25 cm , convex lens will be required.
u = - 25 cm , v = - 200 cm ,
1 / v - 1 / u = 1 /f for lens
- 1 / 200 + 1 / 25 = 1 / f
= .04 - .005 = 1 /f
.035 = 1 / f
f = 28.57 cm = 0.2857 m
power = 1 /f
= 1 / 0.2857
= 3.5 D .
i v ) option is correct .

Answer:
Relatively small part of the electromagnetic spectrum
Explanation:
Let us take a look at the electromagnetic spectrum
Radio waves
Wavelength = 
Microwaves
Wavelength = 
Infrared waves
Wavelength = 
Visible waves
Wavelength = 
Radio waves
Wavelength = 
Ultraviolet waves
Wavelength = 
X ray waves
Wavelength = 
Gamma ray waves
Wavelength = 
So, it can be seen that the visible light makes up a relatively small part of the electromagnetic spectrum.
