Answer:
The wavelength of the light is 530 nm.
Explanation:
Given that,
Distance D= 1.0 m
Distance between slits d= 0.30 mm
Number of fringe = 9
Width = 1.6 cm
We need to calculate the angle
Using formula of angle
We need to calculate the wavelength of the light
Using formula of wavelength
Put the value into the formula
Hence, The wavelength of the light is 530 nm.
Answer: Option (B)
Explanation:
Gas giants are the outer planets that are dominantly comprised of hydrogen and helium. They are Jupiter and Saturn, Whereas ice giants are the outer planets that are composed of mostly ice and ammonia and methane also is present. They are Uranus and Neptune. Both these giant planets are bigger in size in comparison to earth.
The ice giants are far away from the sun, so its very cold and there is abundant ice in the planet.
The <u>main differences between gas giants and ice giants is that, there is the presence of a thick layer of liquid metallic hydrogen in interior part of the gas giants</u>.
The gas giants contains approximately 90% of hydrogen, so when one travels through the interior of this planets, it can be observed that the atmospheric pressure is so extreme that it converts all of its gas into a very highly dense liquid.
Thus, the correct answer is option (B).
Answer:
Explanation:
When a camera shifts focus from a faraway object to a nearby object, the lens-to-film distance must increase. Likewise, when it shifts focus from a nearby object to a distant object, there must be an increase in the lens to film distance (that is, the image distance).
Therefore, if the picture of an object that is far away, the lens must move towards the film.
The focal length cannot be changed because it is fixed for a lens. Nevertheless, in order to focus on an object, the image distance can be changed.
A magnet has a South Pole and a North Pole. South Pole and South Pole can't connect to her other, same as North and North. The same poles push each other away.
South Pole and North Pole connect.
