Amiraneli [1.4K]

The lens' focal length is 1.5 cm, and its focal length is equal to half its radius of curvature, as shown by the formula f=R2 f = R 2, where f seems to be the focal length as well as R is indeed the radius of curvature.

<h3>What does focal length mean?</h3>

When a lens is focussed at infinity, the focal length of the lens is discovered. We can determine the angle of view, or the amount of the scene will be caught, and the magnification, or how big the individual elements will be, by measuring the focal length of the lens. A narrower field of view and a higher magnification result from a longer focal length.

<h3>How do focal length or wavelength work?</h3>

As wavelength and refractive index are inversely connected, the focal length of a lens varies inversely with each of them. The focal length of a lens varies directly with wavelength of light employed. The main reason chromatic aberration occurs is due to this. No relationship exists between the focal length and the frequency of a light.

A bike travels 15.0 km in 45.0 min. Its average speed in km/h is .
Jet001 [13]

Answer:33 3 km/hr

Explanation:

Distance =15 km

Time=45 min

Time =45/100

Time=0.45 hr

Speed=distance ➗ time

Speed=15 ➗ 0.45

Speed =33.3 km/hr
