Answer:
1. It undergoes reflection. 2. It undergoes refraction. 3. It undergoes diffraction.
Explanation:
1. It undergoes reflection. This is because it bounces off surfaces when incident on them.
2. It undergoes refraction. This is because it changes direction when it passes from one medium to another
3. It undergoes diffraction. This is because it spreads out when it passes through doors and windows similar in dimension to the dimensions of its wavelength
 
        
             
        
        
        
Answer:
28 degree C
Explanation:
We are given that 




We have to find the temperature on a spring day when resistance is 215.1 ohm.
We know that 

Using the formula 




Hence, the temperature  on a spring day 28 degree C.
