The transmission of light waves is usually done through cornea of the eyes, then move through another opening which is regarded as pupil before it will get to the retina.

  • Light waves can be regarded as moving energy which contains microscopic particles known as photons.
  • The vision of the eye can be completed through the light wave passing through the components of the eyes and this process goes thus;
  • Light will move through the (cornea) which is situated at the front area of the eyes into lens.
  • Then both the cornea and the lens give room for the focusing of the light rays to the retina which is situated at the back of the eye .
  • Then through the help of the cells in the retina, the light will be absorbed and then be converted to  electrochemical impulses and then transfer it to the brain as well as optic nerve.

Therefore, light wave are form of tiny microscopic particles.

How much thermal energy is required to raise the temperature of 5 kg of water 50℃? The specific heat of water is 4168 J/kg*C.
sasho [114]

Answer/solution:

Given :

Mass =5kg

T 1 =20 C,T 2  =100 ∘C

ΔT=100−20=80 ∘C

Q=m×C×ΔT

where C= specific heat capacity of water

=4200J/(kgK)

Q=5×4200×80

=1680000 Joule.

=1680KJ

Give two examples of chemical energy being transformed into electrical energy
julsineya [31]
It can be used to create electricity and heat and can be found in propane , jet fuel, gasoline and other products. Wood - Dry wood stores chemical energy . This chemical energy is released as the wood burns, and it is burns, and it is converted into heat, which is also called thermal energy, and light energy. ( hope this be helpful)

Value of x<br>Guys plz answer <br>and get marked as brainliest :)​
lakkis [162]

Answer:

80⁰

Explanation:

triangle AOB = 180

So, a = 50

triangle CAB = a+a+x=180

CAB = 50+50+X=180

CAB = X = 180-100

X=80

Please help thank you
Margarita [4]

Answer:

\theta \approx 59.036^{\circ}, T_{2} \approx 23.324\,N

Explanation:

First we build the Free Body Diagram (please see first image for further details) associated with the mass, we notice that system consist of a three forces that form a right triangle (please see second image for further details): (i) The weight of the mass, (ii) two tensions.

The requested tension and angle can be found by the following trigonometrical and geometrical expressions:

\theta = \tan^{-1} \frac{W}{T_{2}} (1)

T_{1} = \sqrt{W^{2}+T_{2}^{2}} (2)

Where:

W - Weight of the mass, measured in newtons.

T_{1}, T_{2} - Tensions from the mass, measured in newtons.

If we know that W = 20\,N and T_{2} = 12\,N, then the requested values are, respectively:

\theta = \tan^{-1} \frac{20\,N}{12\,N}

\theta \approx 59.036^{\circ}

T_{2} = \sqrt{(20\,N)^{2}+(12\,N)^{2}}

T_{2} \approx 23.324\,N
