Gravitational potential energy stored in cat= mgh ( m= mass of cat, h = height of cat from ground) = 7x9.8x3 = 205.8 J
Answer:
The wavelength of the yellow light in given transparent material is <em><u>337 nm</u></em>
Explanation:
Speed of the light in vacuum , 
Therefore speed of light in the given material is 
=>
frequency of yellow light , 
Wavelength in the given transparent material , 
=> 
=>
Thus the wavelength of the yellow light in given transparent material is <em><u>337 nm</u></em>
