A reference point is a point in geometry or general which is used to determine or refer to another point. In reference to this point, measurements can be done. Like, a reference point in space is used to measure distance or displacement to another point. A reference point in time is used to measure the time interval of an event. A reference in space-time can be used to measure the speed or detect object's motion. Hence, the following points apply:
→A position from which to measure future distance
→a set of standard units for measuring displacement
→a method for determining the speed of an object
→a way to detect an object’s motion
A reference point provides a way/method to infer information about the object.
The further away from the mid-ocean ridge, the older the rocks are on the ocean floor. Therefore, the ocean floor feature that would contain the newest rocks would be the mid-ocean ridge.
I think it’s D sorry If I’m wrong
Answer:
The correct answer is - separation.
Explanation:
Communication practice is the ability to the explaining or showing emotions in various ways such as reading, talking, expressing, performing, writing, and witnessing or showing signs.
Separation is an example of communication practice with that in this case LGBTQ community showing their expression that they exist and different from others by displaying rainbows and wearing pink clothing.
Thus, the correct answer is - separation.
Answer:
Increase in wavelength of incident wave also increases the spread angle or spread of the interference pattern.
Explanation:
Solution:-
- The diffraction occurs when light bends in the same medium. The bending is the result of light waves "squeezing" through small openings or "curving" around sharp edges.
- Moreover, waves diffract best when the size of the diffraction opening (or grting or groove) corresponds to the size of the wavelength. Hence, light diffracts more through small openings than through larger openings.
- The formula for diffraction shows a direct relationship between the angle of diffraction (theta) and wavelength:
d sin (θ) = m λ
Where,
λ : Wavelength , θ : The spread angle , d : Slit opening or grating
- We can see that the wavelength λ and spread angle θ are related proportionally. So if we increase the wavelength of incident wave we also increase the spread angle or spread of the interference pattern.
