Main answer: 7.68
Supporting answer: Diffraction
Diffraction of light is the phenomenon where the bending of light happens around corners such that it spreads out and illuminates areas where the formation of shadow is expected.
The diffraction of light is divided into two types:
- Fresnel diffraction: Here the division of light is from a point source and incident and diffracted wavelengths are spherical
- Fraunhoffer diffraction: Here the division of light is from a point source or multiple source and incident and diffracted wavelengths are parallel.
Here diffraction grating, is defined as an optical element that divides the light into various wavelengths.
The formula for diffraction is: dsinФ=nλ
where, d is the distance between the slits, Ф is the diffracting angle, n is the order number and λ is the wavelength.
Given, grating is 2090 grooves per centimeter for n=1,
d=n/λ
Then,
Therefore,
dsinФ=nλ
sinФ=nλ/d
Ф=
Therefore, the red light appears at an angle of 7.68

The gravitational force of attraction on an object placed at the surface of the earth is known a weight of the object. The weight of the object is different on different planets because it depends on the gravitational constant.
The weight is defined by the Newton's second law as the product between the mass and the gravitational acceleration, that is
W = mg
And its unit in SI is Newton (N) and Lbf in American Unit.
Therefore the option D is the only correct here. 1600 kilo Newton or 1600kN.
Answer:It will be larger and uprightIt will be larger and uprightupright ,,
Explanation:The image shows that the object (in this case it's candle) is in between the focal point and the mirror itself. In this case the one ray which is parallel to the mirror axis will pass through the focal point where as the second ray will first pass through the focal point and then touches the tip of the candle. If we extend the two rays behind the mirror, we will get the larger and upright image behind the mirror (as shown in the image attached with this post). Hence correct option is (C): It will be larger and upright.
