Answer:10m/s
Explanation:
Wave speed ,v=for
Where π= wavelength=2m
Period =1/f f=frequency of wave
F=1/period
=1/0.2=5Hz
So speed of waves,v=5×2=10m/s
Answer:
the peak wavelength when the temperature is 3200 K = 
Explanation:
Given that:
the temperature = 3200 K
By applying Wien's displacement law ,we have
T = 0.2898×10⁻² m.K
The peak wavelength of the emitted radiation at this temperature is given by
= 
= 
Hence, the peak wavelength when the temperature is 3200 K = 
Answer:
See below
Explanation:
9.7e-6 is 9.7 x 10^-6 move the decimal 6 to the LEFT to get
= .0000097
