Explanation

All electromagnetic waves travel at the same speed through empty space

Electromagnetic waves are formed between electrical and magnetic fields due to vibrations.

Electromagnetic waves travel with the speed of light in free space.

The speed of light is  3*10^8 m/s

Hence, Electromagnetic waves travel at the speed of 3*10^8 m/s.

Explanation

1. Convert all fractions to a common denominator (8):

   • $\frac{3}{4}=\frac{6}{8}$

   • $\frac{5}{8}=\frac{5}{8}$

   • $\frac{1}{2}=\frac{4}{8}$

2. Perform the calculation:

   • $\frac{6}{8}+\frac{5}{8}-\frac{4}{8}=\frac{7}{8}$

3. Convert $\frac{7}{8}$ to decimal:

   • $\frac{7}{8}=0.875\approx 0.87$
