The units used to measure specific heat capacity is Joules per kilogram per Kelvin.
<h3>What is specific heat capacity?</h3>
It is the amount of heat absorbed per kilogram of material when the temperature rises by 1 kelvin.
Specific heat capacity C is the Joules of energy in form of heat per kilogram per Kelvin temperature. The units represented by
C = ___ J/kg.K
Thus, the units used to measure specific heat capacity is Joules per kilogram per Kelvin.

Ig its Air and noise pollution
Answer: Wavelength of 1420nm
Explanation: When Ray's are incident perpendicularly the path lenght(difference) = 2t
Where t is the thickness of film given as 266nm.
For reflection to take place and be seen there must be constructive interference. Condition for this is
2t = (wavelength/n of soapy
water)/2
Therefore we have,
4t = wavelength/1.33
Making wavelength subject of formula,
Wavelength = 4*266nm*1.33
= 1.42*EXP{-6} m
= 1420*EXP{-9}m
Wavelength reflected strongly
Is 1420nm.
NOTE: EXP represent 10^
