The term defined as the change in direction of light when it goes from one medium into a different medium is refraction.
Refraction is the change of direction on the propagation of a beam of light when it passes from a medium to other; this only happens when the light travels at different speeds in both media.
When a beam of light that travels in the air incedes in a slab of glass, part of the beam is reflected (bounces) and part is refracted (it penetrates in the glass and changes the angle).
Also,due to the different speeds of light in air and water, when a beam of light passes from air to water, it refracts.
Answer:
(4) option is correct
Explanation:
Given that,
The conformation of 2-methyl-3-pentanol, as viewed along the C₂-C₃ bond.
We need to find the Newman structures
Using given structures
The structure of 2- methyl-3- pentanol is shown in figure.
Through C₂-C₃ carbon shown the structure of Newman projection in figure.
Here, carbon 2 is in front side and carbon 3 is in back side in the figure.
Hence, (4) option is correct.
The Largest. There are 17 bodies in the solar system whose radius is greater than 1000 km. The composite above shows the Sun and the 5 largest planets at a scale of 3200 km/pixel. (Earth<span> is the tiny spot between Jupiter and the Sun) so the sun is the largest body in our solar system. hope this helped! ^^</span>
Answer:
334J/g
Explanation:
Data obtained from the question include:
Mass (m) = 1g
Specific heat of Fusion (Hf) = 334 J/g
Heat (Q) =?
Using the equation Q = m·Hf, we can obtain the heat released as follow:
Q = m·Hf
Q = 1 x 334
Q = 334J
Therefore, the amount of heat released is 334J
