Explanation:
given data:
refractive index of lens 1.50
focal length in air is 30 cm
focal length in water is -188 cm
Focal length of lens is given as
![\frac{1}{f} =\frac{n_2 -n_1}{n_1} * \left [\frac{1}{r1} -\frac{1}{r2} \right ]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bf%7D%20%3D%5Cfrac%7Bn_2%20-n_1%7D%7Bn_1%7D%20%2A%20%5Cleft%20%5B%5Cfrac%7B1%7D%7Br1%7D%20-%5Cfrac%7B1%7D%7Br2%7D%20%20%20%5Cright%20%5D)

The material that transmits most light is d) clear glass.
Explanation:
Depending on whether objects can transmit light or not, they can be classified into three types:
- Opaque: an object opaque does not transmit light at all (light cannot pass through an opaque object). Examples of opaque objects are metals
- Translucent: translucent objects allow light to pass partially through them. Examples of translucent objects are fluids
- Transparent: transparent objects allow light to pass through them. An example of transparent objects is clear glass
In this problem, we have the following objects:
- Umbrella: it is opaque, light does not pass through it
- Blanket: it is opaque, light does not pass through it
- Mirror: It is opaque, since it reflects light (light does not pass through it)
- Clear glass: it is a transparent object
Therefore, the material that transmits most light is d) clear glass.
