A glass plate whose index of refraction is 1.66 is immersed in a liquid. The surface of the glass is inclined at an angle of 44º
Anna35 [415]

Answer:

C. 1.15

Explanation:

The formula for the critical angle is:

{sin\theta_{critical}}=\frac {n_r}{n_i}

Where,  

{\theta_{critical}} is the critical angle

n_r is the refractive index of the refractive medium.  ( Alcohol , ? )

n_i is the refractive index of the incident medium.  ( Glass, 1.66 )

<u>Critical angle =  44º</u>

Applying in the formula as:

{sin\theta_{critical}}=\frac {1}{1.523}

{sin\ 44^0}=\frac {n_r}{1.66}

{n_r}=1.15

bekas [8.4K]

Answer:

Explanation:

In an experimental research, the control group is the group that serves as the neutral group that is not given any form of treatment and serves as the group in which the experimental groups are firstly compared to. Thus, <u>the control group in the question described is the Third group</u>.

While experimental groups are the groups that receive treatments required to make an inference from the experiment. From this description, <u>it can be deduced that the First and the Second group are the experimental groups.</u>

Fire spreading from a wall to a nearby couch due to radiant heat transfer is an example of heat reflectivity.

<h3>What is heat reflectivity?</h3>

When sunlight and other light sources strike a material's surface, its reflectance is measured. This number can be used to characterize a surface's characteristics in terms of surface finish. Another name for reflection is reflectivity.

This is a measurement of the amount of energy that material reflects at a specific wavelength. A value between 0 and 1 can also be used to represent reflectivity (or a percentage between 0 and 100).

Sigma and other top businesses have created a range of other forms of heat reflective fabric in the 50 years after the creation of space blankets, including Fabric and aluminum foil laminates, fabric laminates with metalized thin films.
