When you changed from low to high power, how did the change affect the working distance of the lens?

Physics

Basile [38]1 year ago

The working distance gets shorter as the magnification gets bigger. In order to focus, the high-power objective lens must be significantly nearer to the specimen than the low-power lens. Magnification is negatively correlated with working distance.

Magnification change The magnification of a specimen is increased by switching from low power to high power. The magnification of an image is determined by multiplying the magnification of the objective lens by the magnification of the ocular lens, or eyepiece.

The geometry of the optical system connects the magnifying power, or how much the thing being observed seems expanded, and the field of view, or the size of the object that can be seen.

h

Explanation:

Note that the swing direction was not giving in the question and direction could be sideways (in a turn) or in a track or both

The question show something in common ...acceleration

So let's look at the statements and pick the correct ones

a is false while b is correct as the train is accelerating

c is correct. The train is accelerating even thou the speed could not be ascertained

d is false and not feasible as the train is accelerating

e is true as the train maybe moving at a constant speed in a circle

f is false. This could be constant velocity in a circle. Same as g (false)

h is true. It's accelerating

If a star is moving away from you at a constant speed, how do the wavelengths of the absorption lines change as the star gets fa
Minchanka [31]

Answer:

they stay shifted the same amount to the red

Explanation:

Redshift is given by

z=\dfrac{\lambda_o-\lambda_e}{\lambda_e}

Where,

\lambda_o = Wavelength observed

\lambda_e = Wavelength emitted

Also

Transverse redshift is given by

1+z=\dfrac{1}{\sqrt{1-v^2/c^2}}

v = Velocity of object

c = Speed of light = 3\times 10^8\ m/s

So, if the velocity is constant the redshift remains the same
