Answer:
The minimum uncertainty in its speed is greater than 
.
Explanation:
It is given that,
Speed of the particle, 
We need to find the minimum uncertainty in its speed. It can be calculated using uncertainty principle as :
Since, p = mv
So, the minimum uncertainty in its speed is greater than . Hence, this is the required solution.

<u>Answer:</u>
<em>When red light enters the lens its wavelength decreases but its frequency remains the same.
</em>
<u>Explanation:</u>
Lens is made of glass which is a <em>denser medium</em> when compared with air. Thus light will undergo refraction and bend toward the normal. On entering a denser medium from rarer medium the speed of light decreases.
<em>Speed, frequency and wavelength of an electromagnetic wave</em> are related according to the equation.
<em> v=ϑλ
</em>
Where is <em>v is the frequency, λ is the wavelength and v is the speed of the em wave.
</em>
On entering the lens the wavelength of the red light as well as speed decreases but the<em> frequency remains the same.
