A "biconvex" lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvat

madam [21]

Answer:

12 cm

Explanation:

We shall use Lens makers formula here which is as follows

$\frac{1}{F} =(\mu-1) (\frac{1}{R_1} -\frac{1}{R_2})$

Put μ = 1.5 , R₁ = 10 cm ,R₂ = - 15 cm ( according to sign convention )

$\frac{1}{F} =(1.5-1) (\frac{1}{10} -\frac{1}{-15})$

= .5 x ( 15 + 10 ) / 15 x 10

= $\frac{25}{2\times10\times15}$

F = 12 cm

What is the magnitude of the initial velocity?

lesya692 [45]

Magnitude of initial velocity

To calculate the magnitude of the velocity at any point in time, multiply the constant acceleration rate times the time difference and then add it to the initial velocity. As an example, if you dropped a rock off a cliff, its velocity increases by 32 feet per second, every second.
