Answer:
D. A low lambda, λ, and a high nu, ν
Explanation:
- Both x-rays and radio waves are electromagnetic waves that are part of the electromagnetic spectrum.
- <em><u>Radio waves have the longest wavelengths in the electromagnetic spectrum and the lowest frequency.</u></em>
- X-rays on the other hand <em><u>have a higher frequency compared to radio waves and a lower wavelength than that of the radio waves</u></em>.
- All electromagnetic waves in the electromagnetic waves travel with a speed of light, 3.0 × 10^8 m/s. They also posses energy given by the formula E = hf, where h is the plank's constant.
Vo = 8 m/s. g = 10 m/s^2
alpha = 30 degree
ask: x?
x = vo^2 sin ^2 alpha / g
x = 8 ^2 x 2 sin 30 cos 30 / 10
x =( 64 x2x 1/2x1/2√3 )/ 10
x= 3.2 √3 metres
√3 = 1.73
Answer:
B = Bo / 2
Explanation:
Magnesium and electric fields are related in an electromagnetic wave
E / B = c
If the electric field is halved the magnetic field must also be halved to meet the written equation
B = Bo / 2
