What is the wavelength of ultraviolet light whose frequency is 5脳1015Hz?

Short Answer

Expert verified

The wavelength of the ultraviolet light is 60nm.

Step by step solution

01

Identification of given data

The frequency ultraviolet light f=5脳1015Hz

02

Determine the formulas to calculate the wavelength of the ultraviolet light.

The expression to calculate the wavelength is given as follows.

位=vf 鈥�(颈)

Here,谓 is the speed of the light.

03

Determining the wavelength of the ultraviolet light.

Calculate the wavelength of the ultraviolet light.

Substitute5脳1015Hz for f and3脳108m/s for 谓into equation (i).

位=3脳108m/s5脳1015鈥�Hz=3脳10-75鈥�m=0.6脳10-7鈥�m=60nm

Hence the wavelength of the ultraviolet light is 60nm.

The wavelength of red light is about 695nm. What are the frequency and period of this radiation?

If the magnetic field in a particular pulse has a magnitude of 1x10-5T (comparable to the Earth's magnetic field). What is the magnitude of the associated electric field?

A pulse of radiation propagates with velocity <0,0,-c>. The electric field in the pulse is <7.2脳106,0,0>N/C. What is the magnetic field in the pulse?

A slab (pulse) of electromagnetic radiation that is 15cm thick is propagating downward (in the direction) toward a short horizontal copper wire located at the origin and oriented parallel to the z axis, as shown in Figure 23.123. (a) The direction of the electric field inside the slab is out of the page (in the+z direction). On a diagram, show and describe clearly the direction of the magnetic field inside the slab.

(b) You stand on the x axis at location<12,0,0>m, at right angles to the direction of propagation of the pulse. Your friend stands on the z axis at location<0,0,12>m. The pulse passes the copper wire at time t1=0, and at a later time t2 you observe new nonzero electric and magnetic fields at your location, but your friend does not. Explain. What is t2? (Give a numerical answer.) How long a time do these new fields last for you? (c) On a diagram, show and describe clearly the directions of these new nonzero fields (E鈫� and B鈫�) at your location. Explain briefly but carefully.

A point source of green light is placed on the axis of a thin converging lens, 7cm to the left of the lens. The lens has a focal length of 10cm. Where is the location of the image of the source? Is it a real or a virtual image? If you placed a sheet of paper at the location of the image, what would you see on the paper.
