Isla made a diagram to compare x-rays and radio waves. what should isla write in the areas marked a, b, and c? a: has a longer wavelength b: can travel only through matter c: has a higher frequency a: has a higher frequency b: can travel only through matter c: has a longer wavelength a: has a higher frequency b: travels at the same speed c: has a longer wavelength a: has a longer wavelength b: travels at the same speed c: has a higher frequency

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
