Answer:
so his far point according to this pair of glass is 200 cm
Explanation:
power of old pair of corrective glasses is given as
now we have
now we know that for normal vision the maximum distance of vision is for infinite distance
so by lens formula we have
so his far point according to this pair of glass is 200 cm
Answer:
It would cause the lens to produce only real images. It would cause the lens to produce only virtual images. It would make the lens stronger. It would make the lens weaker.

The electric magnet (Electromagnetic) is temporary because you can turn it on and off. When it's power source is gone, the magnet becomes useless. Usually it's power source is a battery, but it could be solar with a switch. Hope this helps. Please give me brainliest is this helps you.
Answer:
constructive λ = 130 m
destructive λ = 260 m
Explanation:
a) the expression for constructive interference is that the difference in amino is equal to a multiple of the average wavelength
AQ - BQ = 2m λ/ 2 m = 0, 1, 2, ...
Where
AQ = 130 +50 = 180 m
BQ = 50 m
To find the smallest wavelength let's use m = 1
180 - 50 = 2 1 λ/ 2
λ = 130 m
b) for destructive interference
AQ –BQ = (2m + 1) λ/2
The smallest value is for m = 0
130 = λ / 2
λ = 260 m
