Question

The increasing order of frequencies for infrared rays, Ultraviolet rays-, X-rays and Y-rays will be-

• A. y-rays, X-rays, Infrared rays, Ulterviolet rays
• B. X-rays,Y-rays Infrared rays,Ultraviolet rays
• C. Infrared rays, Ultraviolet rays,X-rays, Y-rays
• D. Ultraviolet rays,X-rays, Y-rays Infrared rays

Answer 1

The correct option is C Infrared rays, Ultraviolet rays,X-rays, Y-rays

The following are the frequencies ranges

for IF, U.V, X-rays and Y-rays

If rays $-3\times {10}^{11}{h}_2$ $4\times {10}^4{h}_2$

UV rays $-7\times {10}^{14}{h}_2-1.5\times {10}^{15}{h}_2$

x-rays $-3\times {10}^{10}{h}_2-3\times {10}^{19}{h}_2$

r - rays $-3\times {10}^{19}{h}_2-73\times {10}^{19}{h}_2$

Option $-C$ is correct
