Q4 a) Write "True" if the statement is true and write "False" if the statement is false. 1- All bodies emit electromagnetic radiation as a result of thermal motion of their molecules this radiation, called thermal radiation. 2- The rays are the paths of the particles. 3- Reflection at a definite angle from a very smooth surface is called diffuse reflection. 4-The frequency f of the wave change when passing from one material to another. 5- The angle of incidence for which the refracted ray emerges tangent to the surface is called the critical angle, denoted by Ocrit.

8 How does looking at light from distant objects help us predict the temperature of the object? A The light spectrum of the distant object tells us what the object is made of and therefore tells us its temperature. B C D The shape of the object's continuous spectrum tells us its temperature. We can infer the temperature of the object by comparing the spectrum of the object's light with a laboratory spectrum of lines at rest. By estimating the Doppler shift of the object, we can estimate its temperature.
