A short sighted person can not see clearly when an object is placed beyond 80.0cm from his eyes.
(a) What type of lens does he have to use?
(b) calculate the focal length of the lens

You have a scriptbase text Li end text end scriptbase presubscript 3 presuperscript 7 atom (3 protons) which is doubly ionized such that it has just one remaining electron. (scriptbase text Li end text to the power of 2 plus end exponent end scriptbase presubscript 3 presuperscript 7)

How much energy, in electron volts, does it take to remove the remaining electron if it starts in the n = 1 orbital? (to 2 s.f and in eV)

Calculate the speed of light wave propagation in a medium with permittivity e = 9e0 and permeability , u = 4u0 in terms of C

You wish to create a real image with a magnification of −16 (that is an inverted image).

If you have a lens with a focal length of 15 cm, how far away should you place the object?

Light of wavelength 550 nm (in a vacuum) passes through a diamond with a refractive index of 2.42.
What is the wavelength of the light while it is in the diamond?

A person with hypermetropia has a near point of 56 cm. This person wears glasses to correct their vision that have an optical power of +2.7 D.

If this person wears their glasses such that they sit 1.6 cm from their eye, how far away from the glasses is the closest object they can clearly see when wearing their glasses? (to 2 s.f and in cm)

A person with hypermetropia has a near-point of 35 cm and a lens-to-retina distance of 2.0 cm.

What is the maximum optical power of this person's eye? ( to 2 s.f and in D)

Atoms of CO 2 gas decay from upper to lower level with a spread in frequency is about
10kHz. Calculate the line shape if the broadening mechanism is found Doppler
broadening ?

At 300K a mixture of He-Ne is in its ground state, temperature of the system reduced to28K. Which line broadening mechanism will be involved in this transition?

how can we interpret Raman spectra?
