Explanation:
Given that,
The optical power of the equivalent single lens is 45.4 diopters.
(a) The relationship between the focal length and the focal length is given by:
f = 0.022 m
or
f = 2.2 cm
(b) We need to find how far in front of the retina is this "equivalent lens" located. It is given by using lens formula as :
Here, u = infinity
v = 2.2 cm
So, at 2.2 cm in front of the retina is this "equivalent lens" located.
Hence, this is the required solution.
Well, there aren't actually ANY that apply, because you haven't listed any. But I've lived a long time, and I remember hearing about electromagnetic waves and things that use them, so I can list a FEW of them for you:
-- radios
-- TVs
-- garage-door openers
-- TV remotes
-- cell phones
-- smart phones
-- GPS
-- walkie-talkies
-- car headlights
-- lava lamps
-- toasters
-- LEDs
-- light bulbs
-- fluorescent light tubes
-- police radios
-- Doppler weather radars
-- CB radios

-- Bluray recorders and players
-- movie cameras
-- movie projectors
-- reading lamps
-- candles
-- whale-oil lamps
-- kerosene lanterns
-- flashlights
-- campfires
-- coffee percolators
-- heat lamps
-- cordless phones
These are just the ones I can think of right now off the top of my head. There are a lot of others.
Well what are you comparing or try to pair together?
At Korona100 I don’t think it’s 10, becz I remember having this question on my test/ quiz but I got it incorrect so yeah.
