<h2>The atomic mass of silicon is 28.0855</h2>
Answer:
the average kinetic energy of water particles - C.
Given :
An object 50 cm high is placed 1 m in front of a converging lens whose focal length is 1.5 m.
To Find :
the image height (in cm).
Solution :
By lens formula :
Here, u = - 100 cm
f = 150 cm
Now, magnification is given by :
Therefore, the image height is 3 m or 300 cm.
Answer:
Wavelength of the light is 750 nm.
Explanation:
Given that,
Spacing between the lines,
Order of the grating, n = 2
The second order is formed at an angle of 48.5°. The equation of diffraction grating is given by :
or
So, the wavelength of the light is 750 nm. Hence, this is the required solution.
