Points A and F onthe wave are ________ nodespitchtroughscrest3. After randomly polarized light passes through a polarizer, it istotally polarized.partially polarizedtotally blocked.randomly polarized.4. Which type of electromagnetic wave has the most penetrating powerGamma RaysRadio wavesUV RaysX-rays5. Radio carrier waves are generated by causing electrons to oscillate rapidly ina transmitteran antennaa television cameramicrophone6. Total eclipse of the sun occurs whenearth is between the moon and the sunozone layer is threatenedmoon is between the sun and the earthsun is between the moon and the earth7. This types of mirror has a surface that curves inward:Concave MirrorOpaque MirrorConvex MirrorLongitudinal Mirror8. What is the wavelength of light waves if their frequency is 5.0X1014 Hz?0.60 m0.6 micro m6.0 mm0.06 mm9.
